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.
