KVM: x86/mmu: kvm_faultin_pfn has to return false if pfh is returned
commit a7cc099f2ec3117678adeb69749bef7e9dde3148 upstream.
This looks like a typo in 8f32d5e563cb. This change didn't intend to do
any functional changes.
The problem was caught by gVisor tests.
Fixes: 8f32d5e563cb ("KVM: x86/mmu: allow kvm_faultin_pfn to return page fault handling code")
