bridge: mdb: fix double add notification
[ Upstream commit 5ebc784625ea68a9570d1f70557e7932988cd1b4 ]
Since the mdb add/del code was introduced there have been 2 br_mdb_notify
calls when doing br_mdb_add() resulting in 2 notifications on each add.
Example:
Command: bridge mdb add dev br0 port eth1 grp 239.0.0.1 permanent
Before patch:
root@debian:~# bridge monitor all
[MDB]dev br0 port eth1 grp 239.0.0.1 permanent
[MDB]dev br0 port eth1 grp 239.0.0.1 permanent
After patch:
root@debian:~# bridge monitor all
[MDB]dev br0 port eth1 grp 239.0.0.1 permanent
