For nvmet_find_namespace() error case we have inconsistent error code mapping in the function nvmet_get_smart_log_nsid() and nvmet_set_feat_write_protect(). There is no point in retrying for the invalid namesapce from the host side. Set the error code to the NVME_SC_INVALID_NS | NVME_SC_DNR which matches what we have in nvmet_execute_identify_desclist().
