cw1200: Fix spurious BUG_ON() trigger when starting AP mode.
There's an underlying race condition with the unjoin_work() call that is
sometimes triggered depending on scheduling order and the phase of the
moon. This doesn't fix the race condition, but it does remove the
ill-advised BUG_ON() call in an easily-recoverable situation.
