lguest: don't share Switcher PTE pages between guests.
We currently use the whole top PGD entry for the switcher, so we
simply share a fixed page of PTEs between all guests (actually, it's
one per Host CPU, to ensure isolation between guests).
Changes to a scheme where every guest has its own mappings.
