wifi: mac80211: clarify vif handling in TX dequeue

Browse source 
The vif pointer at least looks like it can actually be NULL
in some cases such as the monitor-mode vif, causing static
checkers to complain with the immediate derefence. In these
cases the sta pointer will also be NULL, but clarify it in
the code anyway.
