[PATCH] ppc64 PCI Hotplug: cleanup unsymmetric API routines

Browse source 
This is a minor patch to the ppc64 PCI hotplug code; it makes the call to
rpaphp_unconfig_pci_adapter() symmetric with respect to the call to
rpaphp_config_pci_adapter().  I discussed this with John Rose, who
had provided the last round of changes for these functions; he
appearently had this patch but somehow failed to mail it out.

Tested. (added/removed device).
