Revert "cpufreq: Fix possible race in cpufreq online error path"

This reverts commit 6b0c37b44c89e74ee493241503cc46b5a1fb8a45.

The commit tried to fix a possible real bug but it made it even worse.
The fix was simply buggy as now an error out to out_offline_policy or
out_exit_policy will try to release a semaphore which was never taken in
the first place. This works fine only if we failed late, i.e. via
out_destroy_policy.
