Adding missing break statements causing crash on MSG_SET_EXTRAS.

The case block for MSG_SET_EXTRAS was missing its break statement, all
the way back to summer 2015 when that code was originally added.

When the new MSG_ON_CONNECTION_EVENT handler was added, it introduced a
new potential fall-through from MSG_SET_EXTRAS (in addition to the fact it
too was missing a break statement).
