[libvirt] [PATCH v5 01/16] qemu: Split qemuDomainSetSCSIControllerModel

Rather than one function serving two purposes, let's split things
up into qemuDomainResetSCSIControllerModel for all current callers
and then add qemuDomainCheckSCSIControllerModel when building the
controller command line to check the capabilities.
