Subject: [PATCH] staging/wilc1000: let wilc_mac_xmit() to NETDEV_TX_OK

The method ndo_start_xmit() is defined as returning an 'netdev_tx_t',
which is a typedef for an enum type defining 'NETDEV_TX_OK' but this
driver returns '0' instead of 'NETDEV_TX_OK'.

Fix this by returning ''NETDEV_TX_OK' instead of 0.
