When a socket wants to send, the network interface checks if the socket already exists in the qdisc before adding it.

The qdisc functions do this by checking if the CompatSockets tagged pointer (see compatsocket_toTagged) exists in the queue. The problem is that you can have multiple different tagged pointers that point to the same underlying socket. This isn't an issue for the LegacySockets since the tagged pointer is constructed using the LegacySockets address, but this is an issue for rust InetSockets where the tagged pointer is constructed using the InetSockets address, and there may be multiple InetSockets for a single TcpSocket object. This is because LegacySockets control their own reference counting, whereas a TcpSocket uses separate objects (Arcs) for reference counting, and each InetSocket contains a different Arc that might point to the same TcpSocket.

These qdisc queues should be checking if any sockets with the same canonical handle are in the queue, rather than checking if any sockets have the same socket address.

This bug isn't currently being triggered since we don't actually add rust sockets to the network interface yet.
