Remove hack used to deal with ifnet teardown now that if_detach and the
bridge do a better job.
o move ether_ifdetach to the top of ieee80211_detach
o do not clear if_softc at the top of ieee80211_detach; we no longer need
this because we are safeguarded against calls coming back through if_ioctl
o simplify the bpf tracker now that we don't null if_softc
This also fixes an issue where having a bpf consumer active when a vap
is destroyed would cause a crash because bpf referenced free'd memory.
