fsmonitor: do not nuke dirstate filecache

In the future, chg may prefill repo's dirstate filecache so it's valuable
and should be kept. Previously we drop both filecache and property cache for
dirstate during fsmonitor reposetup, this patch changes it to only drop
property cache but keep the filecache.
