[libvirt] [PATCH 2/4] qemu: Check QEMU_CAPS_OBJECT_IOTHREAD for qemuDomainPinIOThread
https://bugzilla.redhat.com/show_bug.cgi?id=1249981
When trying to pin the thread to the live process in qemuDomainPinIOThread,
there was no check whether the binary supported IOThreads, thus thread_id = 0
(eg current) would be erroneously used.
Follow qemuDomainChgIOThread and only check for the bit if changing
the live definition vs. changing the persistent definition.
