HID: elan: Fix potential double free in elan_input_configured
'input' is a managed resource allocated with devm_input_allocate_device(),
so there is no need to call input_free_device() explicitly or
there will be a double free.
According to the doc of devm_input_allocate_device():
* Managed input devices do not need to be explicitly unregistered or
* freed as it will be done automatically when owner device unbinds from
* its driver (or binding fails).
Fixes: b7429ea53d6c ("HID: elan: Fix memleak in elan_input_configured")
Fixes: 9a6a4193d65b ("HID: Add driver for USB ELAN Touchpad")
