Commit Message

Fix memory leak in UDP engine on truncated group size

When the group_size byte in a received UDP packet exceeds the actual
payload length, in_event() returns early without calling msg.close().
Since msg_t has no destructor, the allocated message memory is
permanently leaked. Repeated packets exhaust process memory.

Add msg.close() before the early return, matching the cleanup pattern
used elsewhere in the same function (e.g., line 564).
