ltop fix to run without MDTs or OSTs

commit 6ec5155 did part of the work to allow ltop to run and show a file system for which only MDTs are running, or only OSTs are running. However one code path was overlooked, and this commit fixes that. ltop should now report on any file system that has either working OSTs reporting via lmt, OR has working MDTs reporting via lmt.
