This is the case when reading freshly created filesystem.
The error message is like the following:
btrfs_read_superblock: No valid root_backup found!
Since the data from super_roots/root_backups is not actually used -
decided to rework btrfs_newest_root_backup() into
btrfs_check_super_roots() that will only check if super_roots
array is valid and correctly handle empty scenario.
As a result:
* btrfs_read_superblock() now only checks if super_roots array is valid;
the case when it is empty is considered OK.
* removed root_backup pointer from btrfs_info,
which would be NULL in case of empty super_roots.
* btrfs_read_superblock() verifies number of devices from the superblock
itself, not newest root_backup.
