[PATCH 1/2] drm/mediatek: Fix child node refcount handling in early exit

[Javier Carrasco]

Early exits (goto, break, return) from for_each_child_of_node() required
an explicit call to of_node_put(), which was not introduced with the
break if cnt == MAX_CRTC.

Add the missing of_node_put() before the break.
