Get default quota value of a subproject is not ignoring default_quota_class conf

[Erickson Filipe Guedes dos Santos]

When getting the default quota value of a project, actually, the DBQuotaDriver is just checking if the default_quota_class CONF is set to True (As you can see here: https://github.com/openstack/cinder/blob/master/cinder/quota.py#L125). But, this default_quota_class values should not be loaded when getting default quota values to subprojects.

    Fix get default quota values for subprojects

    When getting the default quota value for a project, the DBQuotaDriver
    is just checking if the default_quota_class CONF is set to True.
    But this conf should not be considered when getting default quota
    values for subprojects.

    Previously, when we asked for the default quota values of a
    subproject, the default quota values of the root project was returned.
