Add event handler. Events notify us about things like when a
disassociation frame has arrived.
Nice side effect; As we acknowledge the event reason after receiving
a disassociation frame (which happens pretty often by wi(4) hostap) now,
the FW issues an automatic reassociation, and we do not loose network
connectivity anymore.
