Input: wm97xx: Simplify resource management

Browse source 
Since the commit in the Fixes tag below, 'wm->input_dev' is a managed
resource that doesn't need to be explicitly unregistered or freed (see
devm_input_allocate_device() documentation)

So, remove some unless line of code to slightly simplify it.
