No, it would be more like

        if (nr == PF_VECTOR
            ? (vcpu->arch.exception.nested_apf ||
               nested_vmx_is_page_fault_vmexit(vmcs12, 
vcpu->arch.exception.error_code))
            : (vmcs12->exception_bitmap & (1u << nr)))

but I've sent an RFC patch that also fixes the exit qualification.
