nvme/rdma: Inline nvme_rdma_req_put()

Browse Source 
nvme_rdma_req_complete() and nvme_rdma_req_put() are called in a
row except a single case. Move clearing completion_flags and req
of rdma_req from nvme_rdma_req_put() to nvme_rdma_req_complete(),
and then inline nvme_rdma_req_put() because nvme_rdma_req_put()
does only insert now. To do this, change the type of the second
parameter of nvme_rdma_req_complete() from struct nvme_request
to struct spdk_nvme_rdma_req.

For the exceptional case that only nvme_rdma_req_put() is called,
change nvme_rdma_req_init() to clear rdma_req->req if returned with
error.
