Subject: [PATCH v6-resend 13/17] PCI: rpaphp: kmalloc/kfree slot->name directly

rpaphp tends to use slot->name directly everywhere, and doesn't
ever need slot->hotplug_slot->name.

struct hotplug_slot->name is going away, so convert rpaphp directly
manipulate its own slot->name everywhere, and don't bother touching
slot->hotplug_slot->name.
