[PATCH -next 5/7] crypto: stm32/cryp - Fix PM reference leak on stm32-cryp.c

[Shixin Liu]

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.
