fbdev: Fix fb_find_nearest_mode refresh comparison
Refresh rate nearness is not calculated or reset when nearest resolution
changes.
This patch resets the refresh rate differential measurement whenever a
new nearest resolution is discovered. This fixes two error cases;
first, wherein the first mode's refresh rate differential is never
calculated and second, when the closest refresh rate from a previous
nearest resolution is erroneously preserved.
