[ Upstream commit 0c8bb6eb70ca41031f663b4481aac9ac78b53bc6 ]
As we chain the WR during write request: memory registration, rdma write, local invalidate, if only the last WR fail to send due to send queue overrun, the server can send back the reply, while client mark the req->in_use to false in case of error in rtrs_clt_req when error out from rtrs_post_rdma_write_sg.
