Tobias Klauser 4c0833bcd4 bridge: Fix return values of br_multicast_add_group/br_multicast_new_group ...

If br_multicast_new_group returns NULL, we would return 0 (no error) to
the caller of br_multicast_add_group, which is not what we want. Instead
br_multicast_new_group should return ERR_PTR(-ENOMEM) in this case.
Also propagate the error number returned by br_mdb_rehash properly.
