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.
