ACPI: glue: Skip devices with no type in acpi_device_notify()

Browse Source 
Since all of the users of struct acpi_bus_type use the device type
for matching, devices without a type will not be matched by any of
them, so they can be skipped early in acpi_device_notify().

Update the code accordingly.
