[PATCH -next 2/2] crypto: omap-sham - Fix PM reference leak in omap sham ops

[Zhang Qilong <zhangqilong3@huawei.com>]

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.

Fixes: 604c31039dae4 ("crypto: omap-sham - Check for return value from pm_runtime_get_sync")
