Fixed crash with joystick rumble after disconnection

This prevents continuing a rumble after the first one fails, and fixes a long standing crash issue if rumble is started immediately before the controller is disconnected.

Thanks to @AntTheAlchemist for the key bug report that showed what was happening here.
