[PATCH v7 01/16] platform/x86: lenovo-wmi-helpers: Fix memory leak in lwmi_dev_evaluate_int()

["Derek J. Clark" <derekjohn.clark@gmail.com>]

From: Rong Zhang <i@rong.moe>

lwmi_dev_evaluate_int() leaks output.pointer when retval == NULL (found
by sashiko.dev [1]).

Fix it by moving `ret_obj = output.pointer' outside of the `if (retval)'
block so that it is always freed by the __free cleanup callback.

No functional change intended.
