Fix watchdog function_clause
Commit 0b7c87dc caused diameter_watchdog:restart/2 to start returning 'stop', so that a watchdog process for a listening transport that allowed multiple connections to the same peer would die one watchdog timeout after losing a connection. The new return value was supposed to be passed up to transition/2, but was instead passed to set_watchdog/1, resulting in a function_clause error. The resulting crash was harmless but unseemly. Not detected by dialyzer. Thanks to Aleksander Nycz.
