Sorry for the delay, this code is quite tricky. According to my testing
TLS SW and HW should now work, I hope I didn't regress things on the
sockmap side.

This is not solving all the issues (ugh), apart from HW needing the
unhash/shutdown treatment, as discussed we may have a sender stuck in
wmem wait while we free context underneath. That's a "minor" UAF for
another day..
