UPSTREAM: vhost/vsock: fix vhost virtio_vsock_pkt use-after-free
Stash the packet length in a local variable before handing over
ownership of the packet to virtio_transport_recv_pkt() or
virtio_transport_free_pkt().
This patch solves the use-after-free since pkt is no longer guaranteed
to be alive.
