nvme_cancel_request() is used in error handler, and it is always reliable to cancel request synchronously, and avoids possible race in which request may be completed after real hw queue is destroyed. One issue is reported by our customer on NVMe RDMA, in which freed ib queue pair may be used in nvme_rdma_complete_rq().
