mds: properly trim log segments after scrub repairs something

Before calling MDLog::trim_all(), we need to make sure mdlog get flushed
Otherwise, there can be zero expiring log segments. This can cause
MDSGatherBuilder to malfunction. (MDSGatherBuilder::activate() does not
execute empty MDSGatherBuilder's finish context)
