[PATCH] drm/bridge:tc358767: Add of_node_put() when breaking out of loop

[Liang He]

In tc_probe_bridge_endpoint(), we should call of_node_put() when
breaking out of the for_each_endpoint_of_node() which will automatically
increase and decrease the refcount.

Fixes: 71f7d9c03118 ("drm/bridge: tc358767: Detect bridge mode from connected 
endpoints in DT")
