nvme-rdma: avoid repeated request completion
The request may be executed asynchronously, and rq->state may be changed to IDLE. To avoid repeated request completion, only MQ_RQ_COMPLETE of rq->state is checked in nvme_rdma_complete_timed_out. It is not safe, so need adding check IDLE for rq->state. Signed-off-by: Sagi Grimberg <sagi@grimberg.me> Signed-off-by: Chao Leng <lengchao@huawei.com> Signed-off-by: Christoph Hellwig <hch@lst.de>
