devfreq: Allow bw_hwmon resume with zero resume freq

Browse source 
Currently bw_hwmon governor does not allow the device
to be resume if the resume_freq is set to zero. But there
can be devices that vote for zero frequency when there is
no bandwidth on the device. This does not mean that the device
should not be resume from suspend. Remove the check with prevents
resume, instead add a check in the devfreq framework to check if
device is suspended or not before calling the governor resume.
