cluster/dht: Fix dht_setxattr to follow files under migration
If a file is under migration, any xattrs created on it
are lost post migration of the file. This is because
the xattrs are set only on the cached subvol of the source
and as the source is under migration, it becomes a linkto file
post migration.
