scsi: hisi_sas: Don't check .nr_hw_queues in hisi_sas_task_prep()
Now that v2 and v3 hw expose their HW queues (and so shost.nr_hw_queues is
set), remove the conditional checks in hisi_sas_task_prep().
This change would affect v1 HW performance (as it does not expose HW
queues), but nobody uses it and support may be dropped soon.
