KVM: x86/mmu: Use yield-safe TDP MMU root iter in MMU notifier unmapping
Use the yield-safe variant of the TDP MMU iterator when handling an
unmapping event from the MMU notifier, as most occurences of the event
allow yielding.
Fixes: e1eed5847b09 ("KVM: x86/mmu: Allow yielding during MMU notifier unmap/zap, if possible")
