[media] usbvision: Use setup_timer 

Author: Julia Lawall <Julia.Lawall@lip6.fr>

Convert a call to init_timer and accompanying intializations of
the timer's data and function fields to a call to setup_timer.

A simplified version of the semantic match that fixes this problem is as
follows: (http://coccinelle.lip6.fr/)

// 
@@
expression t,f,d;
@@

-init_timer(&t);
+setup_timer(&t,f,d);
-t.data = d;
-t.function = f;
// 

The semantic patch also changes the cast to long to a cast to unsigned
long in the data initializer, as unsigned long is the type of the data field.
