[libvirt] [PATCH 2/9] conf: Rework and rename virDomainDeviceFindControllerModel

As it turns out virDomainDeviceFindControllerModel was only ever
called for SCSI controllers using VIR_DOMAIN_CONTROLLER_TYPE_SCSI
as a parameter.
So rename to virDomainDeviceFindSCSIController and rather than
return a model, let's return a virDomainControllerDefPtr to let
the caller reference whatever it wants.
