[libvirt] [PATCH 2/3] qemu: add a check for non-migratable cpu flags

If user set this feature in vm xml:

  <cpu mode='host-passthrough'>
    <feature policy='require' name='invtsc'/>
  </cpu>

we won't report error when do migrate.

So remove def->cpu->mode check, because we can set feature for
host-passthrough model now.
