cw1200: fix queue locking
Fixes a very rare BUG_ON in cw1200_tx by reserving extra queue slots for
an overflow scenario.
It's possible for a parallel TX to happen when in softap since there are
two interfaces (wlan1 and mon.wlan1). Softirq may switch from one thread
to another asynchronously. In such a case __ieee80211_tx may call driver
tx callback just before a queue is locked.
