> When connect() is scheduled out awaiting TCP_SYN_SENT -> TCP_ESTABLISHED,
> socket may already transition TCP_ESTABLISHED -> TCP_CLOSING
> (VIRTIO_VSOCK_OP_RST) or have sk_err set (VIRTIO_VSOCK_OP_RW). Short
> circuit the logic; do not assume a non-zero sk_err signifies a failed
> connect. connect() should return the status of connection attempt itself,
> not what followed.
