media: exynos4-is: Fix several reference count leaks due to pm_runtime_get_sync
[ Upstream commit 7ef64ceea0008c17e94a8a2c60c5d6d46f481996 ]
On calling pm_runtime_get_sync() the reference count of the device
is incremented. In case of failure, decrement the
reference count before returning the error.
