[PATCH net-next] net: hamradio: fix return type of ndo_start_xmit function

[YueHaibing]

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.
