crypto: omap-sham - Fix PM reference leak in omap sham ops
[ Upstream commit ca323b2c61ec321eb9f2179a405b9c34cdb4f553 ]
pm_runtime_get_sync will increment pm usage counter
even it failed. Forgetting to putting operation will
result in reference leak here. We fix it by replacing
it with pm_runtime_resume_and_get to keep usage counter
balanced.
