Trace URI on the existing CRITICAL message when a body exists but HTTP
return code was Informational responses (100 – 199), no-content (204),
or not_modified (304).

Tested: With these changes, the URI is traced on the CRITICAL message:

```
 curl --http2 -k -H "Content-Type: application/json" \
 -d '{"PowerRestorePolicy":"LastState"}' \
 -X PATCH https://${bmc}/redfish/v1/Systems/system
