When aborting in-flight request for recovering controller, we have
to make sure that queue's complete function is called on completed
request before moving on. Otherwise, for example, the warning of
WARN_ON_ONCE(qp->mrs_used > 0) in ib_destroy_qp_user() may be
triggered on nvme-rdma.
Fix this issue by using blk_mq_tagset_wait_completed_request.
