gpio: sysfs: fix memory leak in gpiod_export_link
commit 0f303db08df0df9bd0966443ad6001e63960af16 upstream.
Fix memory leak in the gpio sysfs interface due to failure to drop
reference to device returned by class_find_device when creating a link.
Fixes: a4177ee7f1a8 ("gpiolib: allow exported GPIO nodes to be named
using sysfs links")
