This resolves an ordering issue that prevented quotas from being applied. XFS quotas are applied recursively, but only for subdirectories created after the quota is applied; if we create `_data` before the quota, and then use `_data` for all data in the volume, the quota will never be used by the volume. Also, add a test that volume quotas are working as designed using an XFS formatted loop device in the system tests. This should prevent any further regressions on basic quota functionality, such as quotas being shared between volumes. Fixes #25368 Signed-off-by: Matt Heon <mheon@redhat.com>
