[PATCH 2/4] firmware/edd: use kobject_put() on edd_device_register() failure

[Tarun Sahu]

When edd_device_register() fails after initializing the kobject with
kobject_init_and_add(), calling kfree(edev) directly bypasses the
kobject release callback (edd_release) and leaks the allocated kobject
resources.

Fix this by replacing direct kfree(edev) with kobject_put(&edev->kobj) on
registration failure.
