Subject: cxgb4vf: fix t4vf_eth_xmit()'s return type
Patch-mainline: v5.9-rc1
Git-commit: 2a78478439317bb18eafb834e10b0dc02c1e53c2
References: jsc#SLE-15131

The method ndo_start_xmit() is defined as returning an 'netdev_tx_t',
which is a typedef for an enum type, but the implementation in this
driver returns an 'int'.

Fix this by returning 'netdev_tx_t' in this driver too.
