wpa_supplicant AP: Make sure deauth/disassoc event is valid

Browse source 
Verify that the driver wrapper is using a valid deauth/disassoc
event before dereferencing the addr pointer. The address is required
to be set in AP mode, but it is safer to verify this here than to
trust on all driver wrappers doing the correct thing.
