As a trivial cleanup this looks fine, but I really hate the structure
of this code.

Can't we have local variables that we set to the dhchap_status and
dhchap_step, and then after the done label just conditionally assign
them if dhchap_status is non-zero?  This should clean up a lot of
mess, especially we'd be done to very few assignments of the step,
and we could avoid jumping out of the switch entirely.
