rS319214: Enforce the limit on ICMP messages before doing work to formulate the

Summary

Enforce the limit on ICMP messages before doing work to formulate the

Delete an unneeded rate limit for UDP under IPv6. Because ICMP6
messages have their own rate limit, it is unnecessary to apply a
second rate limit to UDP messages.
