In one of the error paths of the for_each_child_of_node() loop in
fimc_md_parse_one_endpoint, add missing call to of_node_put().

Fix the following coccicheck warning:
./drivers/media/platform/exynos4-is/media-dev.c:489:1-23: WARNING:
Function "for_each_child_of_node" should have of_node_put() before
return around line 492.

Reported-by: Abaci Robot <abaci@linux.alibaba.com>

You ignored the comment for this. Anyone can run Coccinelle and it
does not equal "Reported-by" credit. Reported by is for reported bugs,
but I asked three times to you guys to share the reports. This is not
an open way of working.

This should be removed.

Best regards,
Krzysztof
