When vcpu placement is "auto", the domain process will be pinned
to advisory nodeset from querying numad, While emulatorpin will
override the pinning. That means both of them are to set the
pinning policy for domain process, but conflicts with each other.
This patch prohibit specifiying emulatorpin if vcpu placement
is "auto". See more details in PATCH 1/7.
