[PATCH] quota-tools: Set FS_DQ_TIMER_MASK for individual xfs grace times

[Eric Sandeen <sandeen@redhat.com>]

xfs quota code doesn't currently allow increasing an individual
user's grace time, but kernel patches are in development for this.

In order for setquota to be able to send this update via
setquota -T, we need to add the FS_DQ_TIMER_MASK when we are trying
to update the grace times on an individual user's dquot.

I wonder if we should only be setting the LIMIT_MASK only if
(flags & COMMIT_LIMITS), but it doesn't seem to be a problem and
is unrelated to this change I'm leaving it alone for now, though if
anyone thinks it's better I can update the patch.

I'm putting together xfstests cases for this, if you want to wait
for those, that's fine.  Thanks!
