KVM: MMU: handle invalid root_hpa at __direct_map
It is possible for __direct_map to be called on invalid root_hpa (-1), two examples: 1) try_async_pf -> can_do_async_pf -> vmx_interrupt_allowed -> nested_vmx_vmexit 2) vmx_handle_exit -> vmx_interrupt_allowed -> nested_vmx_vmexit Then to load_vmcs12_host_state and kvm_mmu_reset_context. Check for this possibility, let fault exception be regenerated.
