net: cirrus: fix return type of ndo_start_xmit function

YueHaibing · davem330 · commit f3bf939f3d45 · 2018-09-21T19:15:14.000-07:00
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.
