[PATCH] xfs: test that default grace periods init on first mount

[Eric Sandeen <sandeen@redhat.com>]

There's currently a bug in how default grace periods get set up
before the very first quotacheck runs; we try to read the quota
inodes before they are populated, and so the grace periods remain
empty.  The /next/ mount fills them in.  This is a regression test
for that bug.
