net: introduce IFF_NO_RX_HANDLER
Some network devices - notably ipvlan slave - are not compatible with any kind of rx_handler. Currently the hook can be installed but any configuration (bridge, bond, macsec, ...) is nonfunctional. This change allocates a priv_flag bit to mark such devices and explicitly forbid installing a rx_handler if such bit is set. The new bit is used by ipvlan slave device.
