Btrfs: avoid double free of fs_info->qgroup_ulist When btrfs_read_qgroup_config or btrfs_quota_enable return non-zero, we've already freed the fs_info->qgroup_ulist. The final btrfs_free_qgroup_config called from quota_disable makes another ulist_free(fs_info->qgroup_ulist) call. We set fs_info->qgroup_ulist to NULL on the mentioned error paths, turning the ulist_free in btrfs_free_qgroup_config into a noop.
