video: fbdev: intelfb: delete double assignment 

Delete successive assignments to the same location.

In the second case, = is converted to |=, which looks appropriate based on
the values involved.

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

// <smpl>
@@
expression i;
@@

*i = ...;
 i = ...;
// </smpl>
