kernel-device: add get_interface_number() method

Browse Source 
We already have methods to query for interface specific attributes
like class/subclass/protocol, so add a new one for the interface
number, and make sure we use ATTRS{bInterfaceNumber} to load it
always, instead of assuming the ID_USB_INTERFACE_NUM property is set.
