mac80211: assign bss_conf.bssid only once
Instead of checking every time bss_info_changed is called, assign the pointer once depending on the interface type and then leave it untouched until the interface type is changed. This makes the ieee80211_bss_info_change_notify() now a simple wrapper to call the driver only. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
