media: i2c: tvp5150: Add of_node_put() before goto
Each iteration of for_each_available_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 four places.
Issue found with Coccinelle.
