cfg80211: fix WoWLAN wakeup tracing

commit a92eecbbeaf01ea2267751569dd3301248513915 upstream.

If the device reports a non-wireless wakeup reason, the
tracing code crashes trying to dereference a NULL pointer.
Fix this by checking the pointer on all accesses and also
add a non_wireless tag to the event.
