cluster/dht: Don't set posix acls on linkto files

Posix acls on a linkto file change the file's permission
bits and cause DHT to treat it as a non-linkto file.This
happens on the migration failure of a file on which posix
 acls were set.

The fix prevents posix acls from being set on a linkto
file and copies them across only after a file has
been successfully migrated.
