Pavel Hrdina a6886aafac qemu: fix crash in qemuDomainSetBlkioParameters without cgroups
If we don't have cgroups available and user tries to update blkio
parameters for running VM it will crash.

It should have been protected by the virCgroupHasController() check but
it was never called if the API was executed without any flags.

We call virDomainObjGetDefs() which sets `def` and `persistentDef` based
on the flags and these two variables should be used to figure out if we
need to update LIVE, CONFIG or both states.

==============================
Libvirt API for virtualization
==============================

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.

For some of these hypervisors, it provides a stateful management
daemon which runs on the virtualization host allowing access to the
API both by non-privileged local users and remote users.

Layered packages provide bindings of the libvirt C API into other
languages including Python, Perl, PHP, Go, Java, OCaml, as well as
mappings into object systems such as GObject, CIM and SNMP.

Further information about the libvirt project can be found on the
website:
