[PATCH v2] IB/ipatch: Use setup_timer and mod_timer

[PATCH v2] IB/ipatch: Use setup_timer and mod_timer

[Vaishali Thakkar]

Use timer API functions setup_timer and mod_timer instead
of structure assignments as they are standard way to set
the timer and to update the expire field of an active timer
respectively.

This is done using Coccinelle and semantic patch used for
this is as follows:

// <smpl>
@@
expression x,y,z,a,b;
@@

-init_timer (&x);
+setup_timer (&x, y, z);
+mod_timer (&a, b);
-x.function = y;
-x.data = z;
-x.expires = b;
-add_timer(&a);
// </smpl>
