vsock: add 'struct vsock_sock *' param to vsock_core_get_transport()
Since now the 'struct vsock_sock' object contains a pointer to the transport, this patch adds a parameter to the vsock_core_get_transport() to return the right transport assigned to the socket. This patch modifies also the virtio_transport_get_ops(), that uses the vsock_core_get_transport(), adding the 'struct vsock_sock *' parameter.
