Log Message:
Plug an mbuf leak.  Found by inspection.

Do not clear IFF_OACTIVE and reset the transmit watchdog timer
unless we have actually freed some transmit resources.  This prevents
my wireless routers from needlessly entering ath_start() without
any transmit resources.  If the MAC's transmitter has frozen, also,
then the driver will take the "out of xmit buffers" path in
ath_start(), which sets OACTIVE without activating the transmit
watchdog.  That freezes the transmit path until the driver is reset.

XXX The "out of xmit buffers" path in ath_start() needs more
XXX attention.
