ufshci: pass the queue being destroyed to the cmd descriptor teardown

ufshci_req_sdb_destroy() hardcoded &ctrlr->transfer_req_queue when
destroying command descriptors instead of using its req_queue argument.

No functional change: the branch only runs for the transfer queue, so
the two pointers are always the same today. Using the argument keeps
the function queue-agnostic for when more transfer queues exist (MCQ).
