net: bridge: multicast: factor out port multicast context

Factor out the port's multicast context into a separate structure which will later be shared for per-port,vlan context. No functional changes intended. We need the structure even if bridge multicast is not defined to pass down as pointer to forwarding functions. Signed-off-by: Nikolay Aleksandrov <[email protected]> Signed-off-by: David S.
