sfc/siena: Remove duplicate check on segments

Siena only supports software TSO. This means more code can be deleted,
as pointed out by the Smatch static checker warning:
	drivers/net/ethernet/sfc/siena/tx.c:184 __efx_siena_enqueue_skb()
	warn: duplicate check 'segments' (previous on line 158)

Fixes: 956f2d86cb37 ("sfc/siena: Remove build references to missing functionality")
