Toshiaki Makita 7bb90c3715 bridge: Fix problems around fdb entries pointing to the bridge device
Adding fdb entries pointing to the bridge device uses fdb_insert(),
which lacks various checks and does not respect added_by_user flag.

As a result, some inconsistent behavior can happen:
* Adding temporary entries succeeds but results in permanent entries.
* Same goes for "dynamic" and "use".
* Changing mac address of the bridge device causes deletion of
  user-added entries.
* Replacing existing entries looks successful from userspace but actually
  not, regardless of NLM_F_EXCL flag.

Use the same logic as other entries and fix them.
