Mark flush request as IDLE in its .end_io(), aligning it with how normal requests behave. The flush request stays in in-flight tags if we're not using an IO scheduler, so we need to change its state into IDLE. Otherwise, we will hang in blk_mq_tagset_wait_completed_request() during error recovery because flush the request state is kept as COMPLETED.
