tier/detach: Clear tier-fix-layout-complete xattr after migration threads join

Previously we had wrongly placed the clearing tier-fix-layout-complete
xattr before the joining of migration threads. This would lead to
situations where failure of clearing the xattr would cause the
premature death of migration threads.

Now we clear the xattr only after the data movement threads join,
ensuring that all migration is done.
