Subject: qemu_hotplug: rename dev to match in qemuDomainDetachDeviceLive


I'm about to add a second virDomainDeviceDef to this function that
will point to the actual device in the domain object. while this is
just a partially filled-in example of what to look for. Naming it
match will make the code easier to follow.
