commit c8d329f311c4d3d8f8e6dc5897ec235e37f48ae8 upstream.
Long ago, group & project quota were mutually exclusive, and so when we turned on XFS_QMOPT_ENOSPC ("return ENOSPC if project quota is exceeded") when project quota was enabled, we only needed to disable it again for user quota.
When group & project quota got separated, this got missed, and as a result if project quota is enabled and group quota is exceeded, the error code returned is incorrectly returned as ENOSPC not EDQUOT.
Fix this by stripping XFS_QMOPT_ENOSPC out of flags for group quota when we try to reserve the space.
