[PATCH] USB Storage: code cleanups for onetouch.c

As sugested by Alan Stern here are a few code cleanups for onetouch.c:

-Check number of endpoints before directly referencing intf->endpoint[2]
-Use defined constants instead of magic numbers
-Revmove the non-ascii characters from copyright notice
-Make registration and deregistration messages more similar
