media: exynos4-is: Fix a reference count leak

[ Upstream commit 64157b2cb1940449e7df2670e85781c690266588 ]

pm_runtime_get_sync() increments the runtime PM usage counter even
when it returns an error code, causing incorrect ref count if
pm_runtime_put_noidle() is not called in error handling paths.
Thus call pm_runtime_put_noidle() if pm_runtime_get_sync() fails.
