crypto: sa2ul - Fix PM reference leak in sa_ul_probe()
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. Signed-off-by: Shixin Liu <liushixin2@huawei.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
