drm: atmel-hlcdc: Fix OF graph parsing

Browse Source 
atmel_hlcdc_create_outputs() iterates over OF graph nodes and releases
the node (using of_node_put()) after each iteration, which is wrong
since for_each_endpoint_of_node() is already taking care of that.

Move the of_node_put() call in the error path.
