CVE-2026-11352: QUIC zero-length UDP datagrams busy-loop

Cherry-picked from 56eca2afb4806f1032872fa9

quic: count zero length packets against max

With a flood of zero lenght UDP packets to curl, the receive loop might
run longer than intended to. Count such packets against the max to
terminate the loop as intended.
