xfs/108: sync filesystem before querying quota

The new deferred inactivation code is lazy about deallocating
deleted files, which means that we need to be more proactive about
syncing the filesystem after deleting things.  When reporting quotas,
XFS only flushes the deferred work if we query quota id 0, so we
need the explicit sync to ensure the quota numbers are not affected
by laziness.
