KVM: x86/mmu: Fix wrong gfn range of tlb flushing in validate_direct_spte()
The spte pointing to the children SP is dropped, so the whole gfn range
covered by the children SP should be flushed. Although, Hyper-V may
treat a 1-page flush the same if the address points to a huge page, it
still would be better to use the correct size of huge page.
Fixes: c3134ce240eed ("KVM: Replace old tlb flush function with new one to flush a specified range.")
