[libvirt] [PATCH v2 02/14] qemu_hotplug: remove extra function in middle of DetachController call chain
qemuDomainDetachDeviceControllerLive() just checks if the controller
type is SCSI, and then either returns failure, or calls
qemuDomainDetachControllerDevice().
Instead, lets just check for type != SCSI at the top of the latter
function, and call it directly.

Change from V1: remove unrelated code movement, per Peter's request.
