Description

In the Linux kernel, the following vulnerability has been resolved:

nvme-rdma: fix -EIO cleanup order in queue_rq

On -EIO, the RDMA queue_rq path reports a host path error and then still cleans up the command and unmaps the SQE DMA. The path error helper completes the request, so that is double cleanup and DMA unmap after the request is already complete.

Unmap the SQE first, then report the host path error. Skip the outer command cleanup on that path.
