sfc: Move TX queue core queue mapping into tx.c
efx_hard_start_xmit() needs to implement a mapping which is the inverse of tx_queue::core_txq. Move the initialisation of tx_queue::core_txq next to efx_hard_start_xmit() to make the connection more obvious. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>
