In preparation to enable -Wimplicit-fallthrough for Clang, fix a couple
of warnings by explicitly adding a break statement and replacing a
comment with a goto statement instead of letting the code fall through
to the next case.

It would go via net/net-next tree, but I can't find this one on
patchwork. Just the previous version.
http://patchwork.ozlabs.org/project/netdev/list/?series=&submitter=&state=*&q=sctp%3A+Fix+fall-through+warnings+for+Clang&archive=both&delegate=
I can, however, find it in the archives.

Thanks, Marcelo.
