KVM: x86/mmu: kvm_faultin_pfn has to return false if pfh is returned 

commit a7cc099f2ec3117678adeb69749bef7e9dde3148 upstream.

This looks like a typo in 8f32d5e563. This change didn't intend to do
any functional changes.

The problem was caught by gVisor tests.

Fixes: 8f32d5e563 ("KVM: x86/mmu: allow kvm_faultin_pfn to return page fault handling code")
