qemu: Fix EmulatorPinInfo without emulatorpin

Browse Source 
https://bugzilla.redhat.com/show_bug.cgi?id=871312

Recent fixes made almost all the right steps to make emulator pinned
to the cpuset of the whole domain in case <emulatorpin> isn't
specified, but qemudDomainGetEmulatorPinInfo still reports all the
CPUs even when cpuset is specified.  This patch fixes that.
