[Bridge] [PATCH net-next v2 1/3] bridge: Set BR_FDB_ADDED_BY_USER early in fdb_add_entry

[Johannes Nixdorf via Bridge]

This allows the called fdb_create to detect that the entry was added by
the user early in the process. This is in preparation to adding limits
in fdb_create that should not apply to user created fdb entries.

Signed-off-by: Johannes Nixdorf <jnixdorf-...@avm.de>

Changes since v1:
 - Added this change to ensure user added entries are not limited.
