cpufreq: Improve error when setting all CPUs to unsupported governor Currently when using set_all_governors to try to set an unsupported governor, the error is a somewhat cryptic "sh: echo: I/O error". Add a check that diagnoses this error. In order to avoid slowing down the "good" path, the check for unsupported governors is only done if the failure has already occured.
