So the quota bit is set (0x40) hence quotas will attempt to be
enabled.

But we have no quota enabled but a user quota inode allocated.
the quota flags would have been written to zero by the initial
failure, so this implies that reading the  user quota inode failed.
Output of 'xfs_db -c "inode 131" -c p /dev/dm-7', please?
