Driver destroy the VNIC when the port is brought down.
Port HW filter setting such as promiscuos, allmulti and
VLAN filtering will be applied when port is started.

Fixed to return success silently for these callbacks
when port is stopped. Also fixed to clear "bp->dev_stopped"
before invoking bnxt_vlan_offload_set_op() in bnxt_dev_start_op().
