This patch (as1230) consolidates code in usb_unbind_interface() and
usb_driver_release_interface(). In fact, it makes release_interface
call unbind_interface, thereby removing the need for duplicated code.
It works like this: If the interface has already been registered with
the driver core when a driver releases it, then the usual driver-core
mechanism will call unbind_interface. If it hasn't been unregistered
then we will make the call ourselves.
As a nice bonus, drivers now don't have to worry about whether their
disconnect method will get called when they release an interface -- it
always will. Previously it would be called only if the interface was
registered.
