Yevgeny Popovych d146a7b9c6 fs: btrfs: Do not fail when all root_backups are empty
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.
