Use new kill_() for _temp_error()

instead of stop(). We really want to require a reset and no chance to set a new temperature.

Marlin/temperature.cpp

     #endif
   }
   #ifndef BOGUS_TEMPERATURE_FAILSAFE_OVERRIDE
-    disable_all_steppers();
-    Stop();
-    while (true) lcd_update();
+    kill_();
   #endif
