John Garry fab09aaee8 scsi: hisi_sas: Stop using queue #0 always for v2 hw
In commit 8d98416a55 ("scsi: hisi_sas: Switch v3 hw to MQ"), the dispatch
function was changed to choose the delivery queue based on the request tag
HW queue index.

This heavily degrades performance for v2 hw, since the HW queues are not
exposed there, and, as such, HW queue #0 is used for every command.

Revert to previous behaviour for when nr_hw_queues is not set, that being
to choose the HW queue based on target device index.
