Prevent some fallthrough warnings we got since gcc7 in aes

Interestingly those can be suppressed with simple comments.
Note that I didn't suppress those in zlib code yet as I'll check for updates for those libs before releasing (while we are pretty much stuck with this AES version unless we put in a lot more work).
