Fix warning if backend registers timer (#91702) (#95363)
currently logger timer is registered default for
cpu/cuda. for other backends, it may or may not
registers this timer. It reports warning for other backends and return which is not expected.
The above may fail, if the backends has have registered this timer. For example, HPU(habana) backend registers this timer. so, in this case it reports a warning and return which is incorrect.
Other case is where lazy backend timer is never registered. so, this returns a warning, and this is the reason the check was added, but it fails for other cases.
Add a generic check if the timer is registered, then don’t report warning.
