mac80211: fix misplaced while instead of if

commit 5981fe5b0529ba25d95f37d7faa434183ad618c5 upstream.

This never was intended to be a 'while' loop, it should've
just been an 'if' instead of 'while'. Fix this.

I noticed this while applying another patch from Ben that
intended to fix a busy loop at this spot.
