Subject: dht - fixing xattr inconsistency

The scenario of setting an xattr to a dir, killing one of the bricks,
removing the xattr, bringing back the brick results in xattr
inconsistency - The downed brick will still have the xattr, but the rest
won't.
This patch add a mechanism that will remove the extra xattrs during
lookup.

This patch is a modification to a previous patch based on comments that
were made after merge:
https://review.gluster.org/#/c/glusterfs/+/24613/

fixes: #1324
