bridge: Use safe default bridge interface

Browse source 
Currently by default, all BSS share the bridge brvlan%d.
While this is sane when no tagged-interface is given, this
is insane when different tagged interfaces are given, as
it would result in bridging those tagged interfaces.

This patch therefore uses br%s%d with %s=tagged_interface
and %d=VLAN ID as bridge name when a tagged-interface is given.
