crypto: omap-aes - Fix PM reference leak on omap-aes.c 

[ Upstream commit 1f34cc4a8da34fbb250efb928f9b8c6fe7ee0642 ]

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.
