xfs: fix assertion failure at xfs_setattr_nonsize
For CRC enabled v5 super block, change a file's ownership can simply
trigger an ASSERT failure at xfs_setattr_nonsize() if both group and
project quota are enabled, i.e,
[ 305.337609] XFS: Assertion failed: !XFS_IS_PQUOTA_ON(mp), file: fs/xfs/xfs_iops.c, line: 621

This fix adjust the assertion to check if the super block support both
quota inodes or not.
