In btrfs, create_pending_snapshot() will go readonly on _any_ error return from btrfs_qgroup_inherit(). If qgroups are enabled, a user can crash their fs by just making a snapshot and asking it to inherit from an invalid qgroup. This patch does exactly that test. If the FS goes readonly that will be reported and we will know that a regression was introduced.
