    net: ovs: fix return type of ndo_start_xmit function

    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.
