bridge: Handle IFLA_ADDRESS correctly when creating bridge device
[ Upstream commit 30313a3d5794472c3548d7288e306a5492030370 ]
When bridge device is created with IFLA_ADDRESS, we are not calling
br_stp_change_bridge_id(), which leads to incorrect local fdb
management and bridge id calculation, and prevents us from receiving
frames on the bridge device.
