qemu: snapshot: Reject internal active snapshot without memory state

A internal snapshot of a active VM with the memory snapshot disabled
explicitly would actually still take the memory snapshot. Reject it
explicitly.

Before:
 $ virsh snapshot-create-as --domain VM --diskspec vda,snapshot=internal --memspec snapshot=no
 Domain snapshot 1401353155 created

After:
 $ virsh snapshot-create-as --domain VM --diskspec vda,snapshot=internal --memspec snapshot=no
 error: Operation not supported: internal snapshot of a running VM must include the memory state
