Review comment:
No, this is a code smell. Better the caller should filter `null` locations,
or that they don't happen at all (see my comments in `MetaRegionLocationCache`
re: storing `null` values in the cache.
This method is also called by `ReopenTableRegionsProcedure`, so I am curious
if there's a test that can exercise the `null` value.
