drm/msm: Switch ordering of runpm put vs devfreq_idle

drm/msm: Switch ordering of runpm put vs devfreq_idle

[ Upstream commit 49e477610087a02c3604061b8f3ee3a25a493987 ]

In msm_devfreq_suspend() we cancel idle_work synchronously so that it
doesn't run after we power of the hw or in the resume path.  But this
means that we want to ensure that idle_work is not scheduled *after* we
no longer hold a runpm ref.  So switch the ordering of pm_runtime_put()
vs msm_devfreq_idle().

v2. Only move the runpm _put_autosuspend, and not the _mark_last_busy()
