USB: gadget: change simple_strtol to simple_strtoul 

Author: Julia Lawall <julia@diku.dk>

Since num is unsigned, it would seem better to use simple_strtoul that
simple_strtol.

A simplified version of the semantic patch that makes this change is as
follows: (http://www.emn.fr/x-info/coccinelle/)

// 
@r2@
long e;
position p;
@@

e = simple_strtol@p(...)

@@
position p != r2.p;
type T;
T e;
@@

e = 
- simple_strtol@p
+ simple_strtoul
  (...)
