of: gpio unittest kfree() wrong object
kernel test robot reported "WARNING: held lock freed!" triggered by
unittest_gpio_remove(). unittest_gpio_remove() was unexpectedly
called due to an error in overlay tracking. The remove had not
been tested because the gpio overlay removal tests have not been
implemented.
kfree() gdev instead of pdev.
Fixes: f4056e705b2e ("of: unittest: add overlay gpio test to catch gpio hog problem")
