metrics: Avoid crash when fetching tier metrics (#14493) 

Data usage does not always contain tiering info even if the data usage
information is valid. Avoid a crash in that case.

(e.g. the scanner scanned the namespace, the user enables tiering,
prometheus scrapes the server before the scanner gets a chance to
update the data usage with new tiering information)
