bridge: mcast: Use MDB configuration structure where possible
The MDB configuration structure (i.e., struct br_mdb_config) now
includes all the necessary information from the parsed RTM_{NEW,DEL}MDB
netlink messages, so use it.
This will later allow us to delete the calls to br_mdb_parse() from
br_mdb_add() and br_mdb_del().
No functional changes intended.
