[PATCH 05/26] Input: maplecontrol - stop polling and clear callback on close

In dc_pad_close(), pass NULL instead of dc_pad_callback to
maple_getcond_callback() to both stop polling and clear the callback
pointer when the input device is closed.

This makes the manual clearing of mdev->callback in
remove_maple_controller() redundant, as input_unregister_device()
automatically closes the device if it was open. Remove the redundant
assignment.
