bridge: Fix potential deadlock on br->multicast_lock
multicast_lock is taken in softirq context, so we should use
spin_lock_bh() in userspace.
call-chain in softirq context:
run_timer_softirq()
br_multicast_query_expired()
call-chain in userspace:
sysfs_write_file()
store_multicast_snooping()
br_multicast_toggle()
