ACPI / hotplug / PCI: Execute _EJ0 under the ACPI scan lock Since acpi_device_hotplug() assumes that ACPI handles of device objects passed to it will not become invalid while acpi_scan_lock is being held, make acpiphp_disable_slot() acquire acpi_scan_lock, because it generally causes _EJ0 to be executed for one of the devices in the slot and that may cause its ACPI handle to become invalid.
