throttle: Merge all functions that check the configuration into one
There's no need to keep throttle_conflicting(), throttle_is_valid() and throttle_max_is_missing_limit() as separate functions, so this patch merges all three into one. As a consequence, check_throttle_config() becomes redundant and can be replaced with throttle_is_valid().
