[PATCH] media: platform: mtk-mdp: mtk_mdp_core: Add of_node_put() before goto

[Nishka Dasgupta]

Each iteration of for_each_child_of_node puts the previous node, but in
the case of a goto from the middle of the loop, there is no put, thus
causing a memory leak. Hence add an of_node_put before the goto in two
places.
Issue found with Coccinelle.
