The acpi_get_pci_rootbridge_handle() walk through the acpi ns to find
the handle matches the seg, bus and the PCI_ROOT_HID_STRING. It should
returns the handle as soon as if find the match. But the current codes
always parse through the whole namespace because the user_function
find_pci_rootbridge() returns status=AE_OK when it finds the match.
This patch, on top of 2.6.19-rc1, is to make the find_pci_rootbridge()
returning AE_CTRL_TERMINATE when it finds the match.
