Subject: [PATCH v3 1/8] [media] soc_camera: Do not decrement endpoint node refcount in the loop

In preparation for a following patch, stop decrementing the endpoint node
refcount in the loop. This temporarily leaks a reference to the endpoint node,
which will be fixed by having of_graph_get_next_endpoint decrement the refcount
of its prev argument instead.
