USB: keep track of whether interface sysfs files exist
This patch (as1009) solves the problem of multiple registrations for
USB sysfs files in a more satisfying way than the existing code. It
simply adds a flag to keep track of whether or not the files have been
created; that way the files can be created or removed as needed.
