ifconfig vlan fix

The vlan driver is calling ieee80211_output() with the wrong ifnet context =
and
dereferencing a bad pointer.

It looks like the passed in if_softc is pointing to a struct ifvlan instead=
 of
the expected struct ieee80211_vap

Looking at vlan_output(), I wonder if the parents ifnet context should be u=
sed
when calling if_output()?

I've attached a patch to show what I mean.
