[libvirt] [PATCH] qemu: Fix emulator affinity
Commit ba63d8f7d843461f77a8206c1ef9da38388713e5 introduced a bug that
makes machines, that don't have either cpuset in <vcpu> or
<emulatorpin> specified, fail. Because the function that sets
affinity is called without any check, the function must not fail
unless there is an error.
