CPUFreq: governors: further cleanups

Hi Rafael,

Here is the third version based on the review comments you gave. I have tried to resolve most of them, and it looks much better now. Thanks for your comments.

As I am traveling this week, don't have access to hardware to retest the series. But I am quite sure it should work just fine, as there weren't lots of updates from how the final code looked earlier. Anyway, I have pushed this for the build bot sometime back and it will let us know of any obvious issues.

V2->V3:
- Few got merged already, and are dropped now
- Patches are reordered a bit to make them more sensible
- gov_queue_work() isn't modified at all with the mask of CPUs, as you suggested earlier.
- Some minor commit/logs updated.

V1->V2:
- Dropped 2/10 from V1 as it wasn't required
- 3/10 saw some changes due to above patch being dropped
- 7/10 changed a bit as we check for pending work items by looking at shared->policy, rather than calling delayed_work_pending. We wanted to check if governor is operational or not and the new check is enough for that.

Viresh Kumar (5):
cpufreq: ondemand: Drop unnecessary locks from update_sampling_rate()
cpufreq: ondemand: update sampling rate immediately
cpufreq: ondemand: queue work for policy->cpus together
cpufreq: governor: Quit work-handlers early if governor is stopped
cpufreq: Get rid of ->governor_enabled and its lock
