PCI: stop leaking 'slot_name' in pci_create_slot

commit 3b5dd45e947ecd21491e1658fba7bb4bc4a54995 upstream.

In pci_create_slot(), the local variable 'slot_name' is allocated by
make_slot_name(), but never freed. We never use it after passing it to
the kobject core, so we should free it upon function exit.
