sfc: remove Software TSO
It gives no advantage over GSO now that xmit_more exists. If we find
ourselves unable to handle a TSO skb (because our TXQ doesn't have a
TSOv2 context and the NIC doesn't support TSOv1), hand it back to GSO.
Also do that if the TSO handler fails with EINVAL for any other reason.
As Falcon-architecture NICs don't support any firmware-assisted TSO,
they no longer advertise TSO feature flags at all.
