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.

This change is not mentioned in the commit message. Also it's not really
functionally important.
Yeah, I was just moving things around in the functions to separate "find
the device", "do type-specific checking", and "do general checking". I
can skip that movement though, and just go directly to the "remove
general checking" in the penultimate patch.
