HID: logitech-hidpp: Fix FF device cleanup on init failure

hidpp_ff_init() creates the input force-feedback device with input_ff_create(), then allocates the HID++ FF private data, effect ID array, and workqueue.

If any of those allocations fail after input_ff_create() succeeds, the function returns an error without destroying the FF device. Add an unwind path that frees the private allocations made by hidpp_ff_init() and calls input_ff_destroy() for failures after input_ff_create() succeeds.
