wcn36xx: Fix DMA channel enable/disable cycle

Right now we have a broken sequence where we enable DMA channel interrupts
which can be left enabled and never disabled if we hit an error path.

Worse still when we unload the driver, the DMA channel interrupt bits are
left intact. About the only saving grace here is that we do remember to
disable the wcnss interrupt when unload the driver.

wcn36xx: implement flush op to speed up connected scan

Without ieee80211_ops->flush implemented to empty HW queues, mac80211 will
do a 100ms dead wait after stopping SW queues, before leaving the operating
channel to resume a software connected scan[1].
(see ieee80211_scan_state_resume)

This wait is correctly included in the calculation for whether or not
we've exceeded max off-channel time, as it occurs after sending the null
frame with PS bit set. Thus, with 125 ms max off-channel time we only
have 25 ms of scan time, which technically isn't even enough to scan one
channel (although mac80211 always scans at least one channel per off-
channel window).

Moreover, for passive probes we end up spending at least 100 ms + 111 ms
(IEEE80211_PASSIVE_CHANNEL_TIME) "off-channel"[2], which exceeds the listen
interval of 200 ms that we provide in our association request frame. That's
technically out-of-spec.

[1]: Until recently, wcn36xx performed software (rather than FW-offloaded)
scanning when 5GHz channels are requested. This apparent limitation is now
resolved -- see commit 1395f8a6a4d5 ("wcn36xx: Enable hardware scan offload
for 5Ghz band").
[2]: in quotes because about 100 ms of it is still on-channel but with PS
set

wcn36xx: add proper DMA memory barriers in rx path

wcn36xx: add proper DMA memory barriers in rx path

This is essentially exactly following the dma_wmb()/dma_rmb() usage
instructions in Documentation/memory-barriers.txt.

The theoretical races here are:

1. DXE (the DMA Transfer Engine in the Wi-Fi subsystem) seeing the
dxe->ctrl & WCN36xx_DXE_CTRL_VLD write before the dxe->dst_addr_l
write, thus performing DMA into the wrong address.

2. CPU reading dxe->dst_addr_l before DXE unsets dxe->ctrl &
WCN36xx_DXE_CTRL_VLD. This should generally be harmless since DXE
doesn't write dxe->dst_addr_l (no risk of freeing the wrong skb).

wcn36xx: Fix tx_status mechanism

This change fix the TX ack mechanism in various ways:

- For NO_ACK tagged packets, we don't need to wait for TX_ACK indication
and so are not subject to the single packet ack limitation. So we don't
have to stop the tx queue, and can call the tx status callback as soon
as DMA transfer has completed.

- Fix skb ownership/reference. Only start status indication timeout
once the DMA transfer has been completed. This avoids the skb to be
both referenced in the DMA tx ring and by the tx_ack_skb pointer,
preventing any use-after-free or double-free.

- This adds a sanity (paranoia?) check on the skb tx ack pointer.

- Resume TX queue if TX status tagged packet TX fails.
