4.17-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Tony Lindgren <t...@atomide.com>

[ Upstream commit 7e48e23a1f4a50f93ac1073f1326e0a73829b631 ]

If pm_runtime_get_sync() fails we should call pm_runtime_put_noidle().
This is probably not a critical fix as we should only hit this when
things are broken elsewhere.
