net: add ndo_fdb_del_bulk

[ Upstream commit 1306d5362a591493a2d07f685ed2cc480dcda320 ]

Add a new netdev op called ndo_fdb_del_bulk, it will be later used for
driver-specific bulk delete implementation dispatched from rtnetlink. The
first user will be the bridge, we need it to signal to rtnetlink from
the driver that we support bulk delete operation (NLM_F_BULK).
