zpool upgrade -v does not show pools, available for upgrade :)

# zpool upgrade
This system is currently running ZFS pool version 28.

All pools are formatted using this version.

sunway  version   28       default

It's latest pool's version for RELENG_9.

Old gptzfsboot must fail with message like this:
ZFS: unsupported ZFS version %u (should be %u)

And why problem solved by copying previous zfsloader?
Without any another changes...
