Janusz Dziedzic 5919a07d71 cfg80211: correct bridge/4addr mode check 
[ Upstream commit 689a0a9f505f7bffdefe6f17fddb41c8ab6344f6 ]

Without the patch we fail:

$ sudo brctl addbr br0
$ sudo brctl addif br0 wlp1s0
$ sudo iw wlp1s0 set 4addr on
command failed: Device or resource busy (-16)

Last command failed but iface was already in 4addr mode.

Fixes: ad4bb6f8883a ("cfg80211: disallow bridging managed/adhoc interfaces")
