fp-bench: remove wrong exponent raise in fill_random
At this point random_ops[] only contains normals, so there's no need to do anything to them. In fact, raising the exponent here can make the output !normal, which is precisely what the comment says we want to avoid. Signed-off-by: Emilio G. Cota <cota@braap.org> Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Signed-off-by: Alex Bennée <alex.bennee@linaro.org>
