We are only interested in domain state so no need to call
virDomainGetInfo for that.

NACK to this, since it breaks migration compatibility. Much of the
'virDomainMigrate' code runs in the client app, and the source
libvirtd it is talking to can't be expected to have virDomainGetState
support. Only the v3 migration could be safely allowed to do this,
and I don't think it is worth it. The reason for using GetState
instead of GetInfo is to avoid calling the monitor, in case QEMU
is deadlocked/blocked, but this isn't useful because the very
next step in migration is going to use the monitor anyway.
