Fix error handling for binlogrouter

Browse Source 
The binlogrouter error handling closed the DCB twice. This was caused by
the change in the way the DCB error handling is done.

The protocol modules now also call the error handling routine even if the
router session is NULL. This enables the binlogrouter to manage
authentication failures correctly instead of trying to reconnect again.
