hostapd: Check that EVENT_ASSOC data is present before using it

Browse source 
While hostapd should not really receive the EVENT_ASSOC message for
IBSS, driver_nl80211.c could potentially generate that if something
external forces the interface into IBSS mode and the IBSS case does not
provide the struct assoc_info data. Avoid the potential NULL pointer
dereference by explicitly verifying for the event data to be present.
