Call cond_resched_lock() when zapping MMIO to reschedule if needed or to release and reacquire mmu_lock in case of contention. There is no need to flush or zap when temporarily dropping mmu_lock as zapping MMIO sptes is done when holding the memslots lock and with the "update in-progress" bit set in the memslots generation, which disables MMIO spte caching. The walk does need to be restarted if mmu_lock is dropped as the active pages list may be modified. Signed-off-by:
