Prevent fuzzer from sending version negotiation packets

This CL is very similar to cl/272244952, except this time for version negotiation (like RETRY, they can't carry frames). It also fixes some minor errors in error handling on the send path (we were returning false instead of zero, so this doesn't change behavior but makes the code more correct) - which should never happen.
