net: bridge: consider only port-VLAN members when flooding

Use the port-VLAN list that is in every master VLAN and consider only
participating port-VLANs when flooding packets. This is the first
optimization that greatly improves performance for sparse port VLANs
e.g. 2 out of 32 ports participating in a single VLAN: before the
bridge would consider all 32 ports and forward the packet only through
the 2, now it will only consider the participating 2 ports.
