[PATCH v3] xfs: new case for test default user/group quota

[Zorro Lang <zlang@redhat.com>]

When default quota is set, all different quota types inherits the
same default value, include group quota. So if a user quota limit
larger than the default user quota value, it will still be limited
by the group default quota value.

An upstream patch for this bug:

  xfs: Split default quota limits by quota type

Hi,

>From suggestion of Eryu(eguan@redhat.com), I change code *return value*
check to *golden image* check in this V3.

Thanks,
Zorro
