From: Sagi Grimberg <sagi@xxxxxxxxxxx> [ Upstream commit fdf58e02adecbef4c7cbb2073d8ea225e6fd5f26 ] 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.
