[PATCH] Input: Fix a ref counting issue

[Christophe JAILLET]

In case of a managed resource, 'devm_input_device_release()' already has a
'input_put_device(dev)' call.

Avoid a double reference decrement by explicitly calling
'input_put_device()' only on non-managed input device.

Fixes: 2be975c6d920 ("Input: introduce managed input devices (add devres 
support)")
