Patch 6 - add exceptions for primate ide/sata controllers.

That won't work, because the cases for IDE and SATA don't always set the
alias (they only set it or machinetypes and controller indexes where it
needs to be an exception).

You need the DomainDefPtr so you check the machinetype with
qemuDomainMachineIs*()
