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. Signed-off-by: Alan Stern <stern@rowland.harvard.edu>
