[PATCH AUTOSEL 5.19 28/73] net: lantiq_etop: Fix return type for implementation of ndo_start_xmit

From: GUO Zihua <redacted>

[ Upstream commit c8ef3c94bda0e21123202d057d4a299698fa0ed9 ]

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.

ltq_etop_tx() would return either NETDEV_TX_BUSY or NETDEV_TX_OK, so
change the return type to netdev_tx_t directly.
