bridge: Don't insert unnecessary local fdb entry on changing mac address
[ Upstream commit 0b148def403153a4d1565f1640356cb78ce5109f ]
The missing br_vlan_should_use() test caused creation of an unneeded
local fdb entry on changing mac address of a bridge device when there is
a vlan which is configured on a bridge port but not on the bridge
device.
Fixes: 2594e9064a57 ("bridge: vlan: add per-vlan struct and move to rhashtables")
