'input' is a managed resource allocated earlier in the function by:
   input = devm_input_allocate_device(&hdev->dev);

There is no need to explicitly free it. This would lead to a double
reference decrement.

Fixes: b7429ea53d6c ("HID: elan: Fix memleak in elan_input_configured")
Fixes: 9a6a4193d65b ("HID: Add driver for USB ELAN Touchpad")
