nvme-rdma: avoid repeated request completion

Browse Source 
[ 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.
