[net80211] log the A-MPDU setup attempt count as part of debugging.

I've seen some cases where we get stuck in a loop constantly trying to
negotiate A-MPDU TX which is definitely not supposed to happen.
This will let me see if it's something funky with the retry count or
not.

Abstract out the ampdu TX pps initialisation code so it can be reused
in the superg fast-frames code.

This harks back to an earlier commit (r280349) where I found that
initialising the pps code with ticks=0 would cause hilariously bad
hz ticks wraparound failures, leading to never actually aggregating
traffic. This is still true for the superg path and so I have to
do the same thing there.

This is a big no-op; a subsequent commit will flip this on so it
works with the fast-frames transmit path.

Tested:

* AR9170, otus(4) - STA mode, 11bg operation
* AR9331, AP mode

Devices like if_rsu don't pass through action/management frames but do send

CALLOUT_MPSAFE has lost its meaning since r141428, i.e., for more than ten

to make them more consistent.

Attempt to address Bug #176201 - don't advertise what the AP announced
to us. Instead, advertise what we can do based on what the AP says and what
we're capped at by the VAP settings.

For non-STA modes we still advertise what our VAP settings are.

It may be that I've over-complicated this and instead of capping things
we can just always announce what we're capable of. But this should at least
stop the blatantly wrong handling of A-MPDU parameters.

(I'll happily simplify things if someone can dig up a replacement, better
compliant behaviour.)

Initialise the pps / packet tracking timestamp so 11n aggregation works again.

There's a bug in the ticks handling where when initialised at '0', once
the ticks counter wrapped the comparison math would never trigger.
The pps calculation would never happen, and thus aggregation was never
enabled.

It manifests itself as "oh you only get 11n transmit aggregation for the
first 10 minutes of uptime."

I'm sure there are other ticks related issues lurking in net80211.

Tested:

* ath / iwn, both with 'wlandebug +11n' and a little bit of iperf to
kick off the transmit A-MPDU negotiation once the pps gets high enough.
