I'm hopefully soon going to take a whack at the USB support for ath(4)
and this'll require some reuse of the busdma memory code.

ath(4): begin fleshing out a "reset type" extension to force cold/warn resets.

Right now the only way to force a cold reset is:

* The HAL itself detects it's needed, or
* The sysctl, setting all resets to be cold.

Trouble is, cold resets take quite a bit longer than warm resets.

However, there are situations where a cold reset would be nice.
Specifically, after a stuck beacon, BB/MAC hang, stuck calibration results,
etc.

The vendor HAL has a separate method to set the reset reason (which is
how HAL_RESET_BBPANIC gets set) which informs the HAL during the reset path
why it occured. This is almost but not quite the same; I may eventually
unify both approaches in the future.

This commit just extends HAL_RESET_TYPE to include both status (eg BBPANIC)
and type (eg do COLD.) None of the HAL code uses it yet though; that'll
come later.

It also is a big no-op in each HAL - I need to go teach each of the HALs
about cold/warm reset through this path.

ath(4) - don't try to free buffers / return an error if we've committed
to transmit the buffer.

ath_tx_start() may manipulate/reallocate the mbuf as part of the DMA
code, so we can't expect the mbuf can be returned back to the caller.
Now, the net80211 ifnet work changed the semantics slightly so
if an error is returned here, the mbuf/reference is freed by the
caller (here, it's net80211.)

So, once we reach ath_tx_start(), we never return failure. If we fail
then we still return OK and we free the mbuf/noderef ourselves, and
we increment OERRORS.

* Use it in the fragment transmit path and ath / uath transmit paths.
* Call it in xmit_pkt() if the transmission fails; otherwise fragments
may be leaked.

This should be a big no-op.
