PCI Hotplug: convert acpi_pci_detect_ejectable() to take an acpi_handle
acpi_pci_detect_ejectable() goes through effort to convert its
struct pci_bus arg to an acpi_handle, but every time we use this
interface, we already have the handle available.
So let's just use the handle instead of converting back and forth.
