Remove all incore use of XFS_OQUOTA_ENFD and XFS_OQUOTA_CHKD. Instead,
start using XFS_GQUOTA_.* XFS_PQUOTA_.* counterparts for GQUOTA and
PQUOTA respectively.
On-disk copy still uses XFS_OQUOTA_ENFD and XFS_OQUOTA_CHKD.
Read and write of the superblock does the conversion from *OQUOTA*
to *[PG]QUOTA*.
