media: s5p-mfc: Fix a reference count leak
[ Upstream commit 78741ce98c2e36188e2343434406b0e0bc50b0e7 ]
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.
Fixes: c5086f130a77 ("[media] s5p-mfc: Use clock gating only on MFC v5 hardware")
