Instead of printing the policy, which is incidentally a kernel pointer,
so with limited interest, print the cpufreq driver name that failed to
be suspend, which is more useful for debugging.

Fixes: 2f0aea936360 ("cpufreq: suspend governors on system suspend/hibernate")

I will drop this tag as this isn't a bug really.
