Why not just call set the status and call nvme_rdma_complete_rq and
return here?
If the err is ENOMEM or EAGAIN, I am not sure the err must be a
path-related error for all HBA drivers. So reused the error check code.
I think it would be more reasonable to assume any errors returned by HBA
driver as path-related errors.
If you think so, I will modify it in next patch version.
Meant to do that only for -EIO. We should absolutely not do any of this
for stuff like EINVAL, EOPNOTSUPP, EPERM or any strange error that may
return due to a bug or anything like that.
ok, please review again, thank you.

Need to do clean. so can not directly return.

goto err_unmap;
