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

[ Upstream commit 9466fcd153f8b89cbaa967af56bcc57140044b8d ]

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.
