drm: radeon: fix sign bug
The "error" variable is unsigned so it's never less than zero. I changed it to check if (freq < current_freq) directly. "best_error" is also unsigned so "best_error - 100" could be a large number instead of a negative. Since "error" is unsigned it is never less than a negative and so the cases where "best_error" is less than or equal to 100 are false.
