Shanzhi Yu d1e460136a qemu: snapshot: Forbid internal snapshot with passthrough devices 
When attempting to create internal system checkpoint with a passthrough
device qemu will report the following error:

error: operation failed: Error -22 while writing VM

This patch calls the function to check if migration is possible with
given VM and thus improves the error to:

error: Requested operation is not valid: domain has assigned non-USB host devices

         LibVirt : simple API for virtualization

  Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
