Subject: net: marvell: fix return type of ndo_start_xmit function

From: YueHaibing <yuehaibing@huawei.com>

[ Upstream commit f03508ce3f9650148262c176e0178413e16c902b ]

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.

Found by coccinelle.
