KVM guest: do not batch pte updates from interrupt context
commit 6ba661787594868512a71c129062ebd57d0c01e7 upstream.
Commit b8bcfe997e4 made paravirt pte updates synchronous in interrupt
context.
Unfortunately the KVM pv mmu code caches the lazy/nonlazy mode
internally, so a pte update from interrupt context during a lazy mmu
operation can be batched while it should be performed synchronously.
https://bugzilla.redhat.com/show_bug.cgi?id=518022
Drop the internal mode variable and use paravirt_get_lazy_mode(), which
returns the correct state.
