qemu: Add check for invalid iothread_id in qemuDomainChgIOThread
https://bugzilla.redhat.com/show_bug.cgi?id=1251886 Since iothread_id == 0 is an invalid value for QEMU let's point that out specifically. For the IOThreadDel code, the failure would have ended up being a failure to find the IOThread ID; however, for the IOThreadAdd code - an IOThread 0 was added and that isn't good. It seems during many reviews/edits to the code the check for iothread_id = 0 being invalid was lost - it could have originally been in the API code, but requested to be moved - I cannot remember. (cherry picked from commit 32c6b1908bbf8a1aa4a2692135e7d02a166a0317)

LibVirt : simple API for virtualization Libvirt is a C toolkit to interact with the virtualization capabilities of recent versions of Linux (and other OSes). It is free software available under the GNU Lesser General Public License. Virtualization of the Linux Operating System means the ability to run multiple instances of Operating Systems concurrently on a single hardware system where the basic resources are driven by a Linux instance. The library aim at providing long term stable C API initially for the Xen paravirtualization but should be able to integrate other virtualization mechanisms if needed.

Description
Libvirt provides a portable, long term stable C API for managing the
virtualization technologies provided by many operating systems. It
includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware
vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER
Hypervisor.
