Input: wm97xx: Simplify resource management
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.
Fixes: c72f61e74073 ("Input: wm97xx: split out touchscreen registering")
