KVM guest: do not batch pte updates from interrupt context
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.
