NTFS: - Change ntfs_cluster_alloc() to take an extra boolean parameter
specifying whether the cluster are being allocated to extend an
attribute or to fill a hole.
- Change ntfs_attr_make_non_resident() to call ntfs_cluster_alloc()
with @is_extension set to TRUE and remove the runlist terminator
fixup code as this is now done by ntfs_cluster_alloc().
