[libvirt] [PATCH] conf: fix no error when set an unsupport string in ./devices/shmem/msi[@ioeventfd]

https://bugzilla.redhat.com/show_bug.cgi?id=1220265 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. Instead of define a int variable in virDomainShmemDefParseXML and use the new defined variable as transition variable. I think define ioeventfd as an 'int' variable will be better.
