SELECT total_log_used from sysibmadm.snapdb (which is used internally by db2_logsizes) returns "-" when writes are suspended in db2.

The check did not consider this edgecase and crashed with ValueError: invalid literal for int() with base 10: '-'. Now the check will go to UNKNOWN and show Can not read usedspace.
