wifi: cw1200: remove RCU STA pointer handling in TX
We can call this in one of two ways: through mac80211, where
we're already in an RCU read-side critical section, or from
some other code in the driver where this pointer can only be
NULL. In any case, we get a 'free' already protected pointer
to the sta through info->control.sta, so we can use it on
the stack without any further protection.
Remove the rcu_dereference() and critical section.
