This prevents 'comp_pktq' from being used in an
incorrect manner.

But there's also the same init later in the function, inside the while loop:
INIT_LIST_HEAD(&rx_pktq);
INIT_LIST_HEAD(&comp_pktq);
Is this intentional?

I think so.
If we break out of the loop on the first iteration because of the condition
"if (id >= ENDPOINT_MAX)", then comp_pktq ends up being used without having
been initialized.
