posix: check before removing stale symlink
BZ 1564071 complains of directories with missing gfid symlinks and
corresponding "Found stale gfid handle" messages in the logs. Hence
add a check to see if the symlink points to an actual directory before
removing it.
Note: Removing stale symlinks was added via commit
