[PATCH] PCI: Fix pci_create_slot() memory leak

[Jubin Zhong]

After commit 8a94644b440e ("PCI: Fix pci_create_slot() reference count
leak"), kobject_put() is called instead of kfree() if
kobject_init_and_add() fails. However, we still need to free the slot
memory before overwriting it as ERR_PTR(err).

This partially reverts the commit 8a94644b440e.
