====================
net: bridge: mcast: simplify allow/block EHT code

The set does two minor cleanups of the EHT allow/block handling code:
patch 01 removes code which is unreachable (it was used in initial EHT
versions, but isn't anymore) and prepares the allow/block functions to be
factored out. Patch 02 factors out common allow/block handling code.
There are no functional changes.

v2: send patch 02 and the proper version of both patches
====================
