[PATCH] video: fbdev: uvesafb.c: Cleaning up variable that is never used

From: Rickard Strandqvist <redacted>

Variable ar assigned a value that is 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

Are you sure this is right fix?

Should we be returning the error when there's error?
