crypto: sa2ul - Fix PM reference leak in sa_ul_probe()
[ Upstream commit 13343badae093977295341d5a050f51ef128821c ]
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.
