[3/5] tc: fix compiler warnings in ip6 pedit
Checks
Commit Message
Gcc-10 complains about referencing a zero size array.
This occurs because the array of keys is actually in the following
structure which is part of the overall selector.
The original code was safe, but better to just use the key
array directly.
