btrfs-progs: check if adding device would overflow while scanning
It's theoretically possible to add multiple devices with sizes that add up
to or exceed 16EiB. A file system will be created successfully but will
have a superblock with incorrect values for total_bytes and other fields.
Kernels up to v5.0 will crash when they encounter this scenario.
We need to check for overflow and reject the device if it would overflow.
TW should already have that version. Leap will need a backport.
