[PATCH for-4.16 3/4] test/tsx: set grant version for created domains

[Roger Pau Monne <roger.pau@citrix.com>]

Set the grant table version for the created domains to use version 1,
as such tests domains don't require the usage of the grant table at
all. A TODO note is added to switch those dummy domains to not have a
grant table at all when possible. Without setting the grant version
the domains for the tests cannot be created.

Fixes: 7379f9e10a ('gnttab: allow setting max version per-domain')

This patch only modifies a test, so it should be safe to commit as
it's not going to cause any changes to the hypervisor or the tools.
Worse that could happen is it makes the test even more broken, but
it's already unusable.
