crypto: sun8i-ss - Fix PM reference leak when pm_runtime_get_sync() fails

stable inclusion
from stable-5.10.36
commit 2264965f576ff434ee7121edc98a83b072d4e645
bugzilla: 51867
CVE: NA

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

[ Upstream commit 06cd7423 ]

pm_runtime_get_sync will increment pm usage counter even it failed.
Forgetting to putting operation will result in reference leak here.
Fix it by replacing it with pm_runtime_resume_and_get to keep usage
counter balanced.
