When userspace requests a deauth while the
authentication work is pending in the auth
(not probe) state, we do not properly abort
the work and then things get confused.
Fix that and also improve the checks here
to include the correct virtual interface,
just in case two virtual interfaces would
ever try to connect to the same BSS.
