[PATCH 4.9 156/222] net: xen-netback: fix return type of ndo_start_xmit function

[Greg Kroah-Hartman]

From: YueHaibing <yuehaibing@xxxxxxxxxx>

[ Upstream commit a9ca7f17c6d240e269a24cbcd76abf9a940309dd ]

The method ndo_start_xmit() is defined as returning an 'netdev_tx_t',
which is a typedef for an enum type, so make sure the implementation in
this driver has returns 'netdev_tx_t' value, and change the function
return type to netdev_tx_t.
