In case of deleting the seed device the %cur_devices (seed) and the %fs_devices (parent) are different. Now, as the parent fs_devices::total_devices also maintains the total number of devices including the seed device, so decrement its in-memory value for the successful seed delete. We are already updating its corresponding on-disk btrfs_super_block::number_devices value.
