scsi: ufs: optimize clock, pm_qos, hibern8 handling in queuecommand
ufshcd_queuecommand() vote for the resources in this order: clocks,
pm_qos latency, hibern8 exit. If any of these votes are not already
applied, each one has to be applied asynchronously and in that case we are
releasing all the previously applied resource votes (for example, if
hibern8 exit has to be completed asynchronously, we release the votes for
pm_qos and clocks as well). This is not a optimal solution instead we
should skip scheduling the unvoting work for already voted resources.
