John Fastabend c42253cc88 bpf: sockmap remove duplicate queue free ... In tcp bpf remove we free the cork list and purge the ingress msg list. However we do this before the ref count reaches zero so it could be possible some other access is in progress. In this case (tcp close and/or tcp_unhash) we happen to also hold the sock lock so no path exists but lets fix it otherwise it is extremely fragile and breaks the reference counting rules. Also we already check the cork list and ingress msg queue and free them once the ref count reaches zero so its wasteful to check twice.
