conf: Make switch statements more strict

Browse Source 
When switching over the values in the virDomainControllerModelPCI
enumeration, make sure the proper cast is in place so that the
compiler can warn us when the coverage is not exaustive.

For the same reason, remove the 'default' case from one of the
existing switch statements.
