When testing a domain XML with TPM we overwrite UNIX socket path to mimic what qemuTPMEmulatorPrepareHost() is doing (because *PrepareHost() functions are not called from the test). But we are not doing it fully - we need to set the chardev's type too so that virDomainTPMDefFree() can free the path.

Ah, good point. Do you trust me enough that I can fix this before pushing or do you want to see v2? ;-)
