Subject: [PATCH] qemu: Fix qemuDomainGetEmulatorPinInfo()

The order of pinning priority (at least for emulator thread) was
set by v1.2.15-rc1~58 (for cgroup code). But later, when
automatic placement was implemented into
qemuDomainGetEmulatorPinInfo(), the priority was not honored.

Now that we have this priority code in a separate function, we
can just call that and avoid this type of error.
