mac80211: fix monitor interface suspend crash regression

commit cd34f647a78e7f2296fcb72392b9e5c832793e65 upstream.

    mac80211: cleanup generic suspend/resume procedures

removed check for deleting MONITOR and AP_VLAN when suspend. That can
cause a crash (i.e. in iwlagn_mac_remove_interface()) since we remove
interface in the driver that we did not add before.
