PCI: SGI Hotplug: stop managing bss_hotplug_slot->name

We no longer need to manage our version of hotplug_slot->name
since the PCI and hotplug core manage it on our behalf.

Update the sn_hp_slot_private_alloc() interface to fill in
the correct name for us, as that function already has all
the parameters needed to determine the name.
