qemuBuildUSBControllerDevStr: Split out validation of USB controller

Browse Source 
Move the validation code into a separate function. For now the
validation is still kept in the commandline format step as simply just
moving it to the validator causes failures in the test suite, which will
need to be investigated deeper.
