parisc: pdc_stable: Fix memory leak in pdcs_register_pathentries
commit d24846a4246b6e61ecbd036880a4adf61681d241 upstream.
kobject_init_and_add() takes reference even when it fails.
According to the doc of kobject_init_and_add()：
If this function returns an error, kobject_put() must be called to
properly clean up the memory associated with the object.
Fix memory leak by calling kobject_put().
Fixes: 73f368cf679b ("Kobject: change drivers/parisc/pdc_stable.c to use kobject_init_and_add")
