wl12xx: Avoid redundant TX work
TX might be handled in the threaded IRQ handler, in which case, TX work
might be scheduled just to discover it has nothing to do.
Save a few context switches by cancelling redundant TX work in case TX
is about to be handled in the threaded IRQ handler. Also, avoid
scheduling TX work from wl1271_op_tx if not needed.
