USB: create attributes before sending uevent
This patch (as1087d) fixes a long-standing problem in usbcore: Device,
interface, and endpoint attributes aren't added until _after_ the
creation uevent has already been broadcast.
Unfortunately there are a few attributes which cannot be created that
early. The "descriptors" attribute is binary and so must be created
separately. The power-management attributes can't be created until
the dev/power/ group exists. And the interface string can vary from
one altsetting to another, so it has to be created dynamically.
