Since Linux now supports CFI, it will be a good idea to fix mismatched return type for implementation of hooks. Otherwise this might get cought out by CFI and cause a panic. As returns from _rtw_xmit_entry() would always be 0, remove unneeded variable ret and use enums from netdev_tx_t as return value instead. Then change return type to netdev_tx_t.
