cluster/dht: Clear clean_dst flag on target change
If the target of a file migration was changed because of min-free-disk limits, the dst_fd was closed but the clean_dst flag was not set to false. If the file could not be created on the new target for some reason, the ftruncate call to clean up the dst was sent on the now invalid fd causing the process to deadlock.
