media: exynos-gsc: fix pm_runtime_get_sync() usage count
[ Upstream commit 59087b6 ] The pm_runtime_get_sync() internally increments the dev->power.usage_count without decrementing it, even on errors. Replace it by the new pm_runtime_resume_and_get(), introduced by: commit dd8088d ("PM: runtime: Add pm_runtime_resume_and_get to deal with usage counter") in order to properly decrement the usage counter, avoiding a potential PM usage counter leak. As a bonus, as pm_runtime_get_sync() always return 0 on success, the logic can be simplified.
