  Fix for bug #22158: Errors in init_connect terminate connections silently
  
  When executing the init_connect statement, thd->net.vio is set to 0, to         
  forbid sending any results to the client. As a side effect we don't log         
  possible errors, either.                                                        
                                                                                  
  Now we write warnings to the error log if an init_connect query                
  fails.
