Pass the return value to an enum directly is not safe.
When pass a invalid @ioeventfd and virTristateSwitchTypeFromString
return -1 to def->msi.ioeventfd, and this value transform to
4294967295, so no error when the parse failed.

To fix this issue, folter the value using int and then assign it
to virTristateSwitch as it's done.

ACK, I reworded the commit message and pushed and I believe there is
no need for a unit test.

Yes, thanks for your quick review.

I wonder why we don't rework out FromString() helpers to parse the
value into a parameter passed as a pointer and return 0/-1 properly.
Probably nobody wanted to mess with half of libvirt code, I guess...

Maybe... :)
