grant-tables: do not fail attempts to GNTTABOP_set_version to the current version.
...even if there are active grants.

This triggers when checkpoint a guest which essentially resumes
without actually having gone through the suspend so the domain is
already latched to v2 inside Xen.

Also return the current actual version on success and failure. Not
terribly useful with only 2 options but is more robust to future
developments.
