mac80211: assign AP_VLAN hw queues correctly

Browse Source 
A lot of code in mac80211 assumes that the hw queues are
set up correctly for all interfaces (except for monitor)
but this isn't true for AP_VLAN interfaces. Fix this by
copying the AP master configuration when an AP VLAN is
brought up, after this the AP interface can't change its
configuration any more and needs to be brought down to
change it, which also forces AP_VLAN interfaces down, so
just copying in open() is sufficient.
