Migration target with a vhost-vsock device in the .post_load() hook issues
VIRTIO_VSOCK_EVENT_TRANSPORT_RESET event to the guest. This results into
the guest tearing down all its vsock connections. That reset exists
because after a normal migration the cid may change.
However it's not true for CPR-style migration. In this case cid remains
the same, and we want the connections to persist. Thus, let's customize
the .post_load() hook to skip the common transport reset part in this case.
