media: exynos4-is: fimc-is: Add of_node_put() when breaking out of loop

[ Upstream commit 211f8304fa21aaedc2c247f0c9d6c7f1aaa61ad7 ]

In fimc_is_register_subdevs(), we need to call of_node_put() for
the reference 'i2c_bus' when breaking out of the
for_each_compatible_node() which has increased the refcount.
