Ktls: never skip stamping tags for NIC TLS
The newer RACK and BBR TCP stacks have added a mechanism to disable hardware packet pacing for TCP retransmits. This mechanism works by skipping the send-tag stamp on rate-limited connections when the TCP stack calls ip_output() with the IP_NO_SND_TAG_RL flag set. When doing NIC TLS, we must ignore this flag, as NIC TLS packets must always be stamped. Failure to stamp a NIC TLS packet will result in crypto issues.
