Jeff Mahoney d29f475108 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.
