PCI: Fix pci_create_slot() reference count leak
[ Upstream commit 8a94644b440eef5a7b9c104ac8aa7a7f413e35e5 ]
kobject_init_and_add() takes a reference even when it fails. If it returns
an error, kobject_put() must be called to clean up the memory associated
with the object.
When kobject_init_and_add() fails, call kobject_put() instead of kfree().
b8eb718348b8 ("net-sysfs: Fix reference count leak in
rx|netdev_queue_add_kobject") fixed a similar problem.
