[PATCH] staging: xgifb: vb_setmode: Removed variables that is never used

[Rickard Strandqvist <rickard_strandqvist@xxxxxxxxxxxxxxxxxx>]

Variable was assigned a value that was never used.
I have also removed all the code that thereby serves no purpose.

This was found using a static code analysis program called cppcheck
