[PATCH 3/3] xfs: adjust the hint based zone allocation policy

[Hans Holmberg <Hans.Holmberg@wdc.com>]

As we really can't make any general assumptions about files that don't
have any life time hint set or are set to "NONE", adjust the allocation
policy to avoid co-locating data from those files with files with a set
life time.
