btrfs-progs: skip fs with no seed when build seed/sprout mapping for fi show

There is no need to try to build seed/sprout mapping for those btrfs
without seed devices, so just skip such fs.
We could get the total number of devices from the disk super block, if it
equals the number of items in list @fs_devices->devices, then there shouldn't
be any seed devices.
