crypto: stm32/cryp - Fix PM reference leak on stm32-cryp.c

BugLink: https://bugs.launchpad.net/bugs/1928825
[ Upstream commit 747bf30fd944f02f341b5f3bc7d97a13f2ae2fbe ]

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.
