bridge: Don't put partly initialized fdb into hash
The fdb_create() puts a new fdb into hash with only addr set. This is not good, since there are callers, that search the hash w/o the lock and access all the other its fields. Applies to current netdev tree. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
