Hi Daniel,

The purpose is to remove this failure check for QEMU v2.12.
In QEMU commit 65ace0604551, it decoupled the RAM status from the active migration status.

The usage scenario is querying migration status at destination side, which may contain
active migration status, but without RAM status, so we will see that libvirt report error here.

The backward is that we loss failure check for QEMU < v2.12.
However, add a QEMU version check here is not graceful.

Can you accept this trade-off? Or better thoughts?

Thanks,
Keqian
