I already checked previously, two place use it.

fwnode_graph_get_endpoint_count(), it will go though all endpoints, last
ep is NULL, which totally equial to scoped() version.

another one fwnode_graph_get_endpoint_by_id(), which return ep, expect
caller to call put().

if use scoped() version, need use no_free_ptr() at return, which make think
a little bit complex.

It'd better leave these as it.
