net: bridge: mcast: fix unused br var when lockdep isn't defined
Stephen reported the following warning:
net/bridge/br_multicast.c: In function 'br_multicast_find_port':
net/bridge/br_multicast.c:1818:21: warning: unused variable 'br' [-Wunused-variable]
1818 | struct net_bridge *br = mp->br;
| ^~
It happens due to bridge's mlock_dereference() when lockdep isn't defined.
Silence the warning by annotating the variable as __maybe_unused.
Fixes: 0436862e417e ("net: bridge: mcast: support for IGMPv3/MLDv2 ALLOW_NEW_SOURCES report")
