dht: do not remove linkfile if file exist in cached sub volume

Currently with rmdir, if a directory contains only the linkfiles
we remove all the linkfiles and this is causing the problem when the cached
sub volume is down and end-up with duplicate files showing on the mount point.

Solution: Before removing a linkfile check if the
files exists in cached subvolume.
