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 [ 305.339250] Kernel BUG at ffffffffa0a7fa32 [verbose debug info unavailable] [ 305.383939] Call Trace: [ 305.385536] [<ffffffffa0a7d95a>] xfs_setattr_nonsize+0x69a/0x720 [xfs] [ 305.387142] [<ffffffffa0a7dea9>] xfs_vn_setattr+0x29/0x70 [xfs] [ 305.388727] [<ffffffff811ca388>] notify_change+0x1a8/0x350 [ 305.390298] [<ffffffff811ac39d>] chown_common+0xfd/0x110 [ 305.391868] [<ffffffff811ad6bf>] SyS_fchownat+0xaf/0x110 [ 305.393440] [<ffffffff811ad760>] SyS_lchown+0x20/0x30 [ 305.394995] [<ffffffff8170f7dd>] system_call_fastpath+0x1a/0x1f [ 305.399870] RIP [<ffffffffa0a7fa32>] assfail+0x22/0x30 [xfs] This fix adjust the assertion to check if the super block support both quota inodes or not.
