[21/26] USB: fix formatting of SuperSpeed endpoints in /proc/bus/usb/devices

[Greg KH <gregkh@suse.de>]

2.6.33-longterm review patch.  If anyone has any objections, please let us know.

------------------

From: Dmitry Torokhov <dtor@vmware.com>

commit 2868a2b1ba8f9c7f6c4170519ebb6c62934df70e upstream.

Isochronous and interrupt SuperSpeed endpoints use the same mechanisms
for decoding bInterval values as HighSpeed ones so adjust the code
accordingly.

Also bandwidth reservation for SuperSpeed matches highspeed, not
low/full speed.
