Stefano Garzarella b605673b52 vsock/virtio: free queued packets when closing socket ... [ Upstream commit 8432b8114957235f42e070a16118a7f750de9d39 ] As reported by syzbot [1], there is a memory leak while closing the socket. We partially solved this issue with commit ac03046ece ("vsock/virtio: free packets during the socket release"), but we forgot to drain the RX queue when the socket is definitely closed by the scheduled work. To avoid future issues, let's use the new virtio_transport_remove_sock() to drain the RX queue before removing the socket from the af_vsock lists calling vsock_remove_sock().
