sfc: make tx_queues_per_channel variable at runtime
Siena needs four TX queues (csum * highpri), EF10 needs two (csum),
and EF100 only needs one (as checksumming is controlled entirely by
the transmit descriptor). Rather than having various bits of ad-hoc
code to decide which queues to set up etc., put the knowledge of how
many TXQs a channel has in one place.
