crypto: sun8i-ce - Fix PM reference leak in sun8i_ce_probe()

stable inclusion
from stable-5.10.36
commit 836671775a6e726215b72b15fa7ca858ba6ae0e8
bugzilla: 51867
CVE: NA

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

[ Upstream commit cc987ae9 ]

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.
