[PATCH v2] net: ethernet: ti: netcp_core: use for_each_available_child_of_node_scoped() in netcp_probe()

["Manush Prajwal" <manushprajwal555@gmail.com>]

Rework the interfaces loop in netcp_probe() around
for_each_available_child_of_node_scoped() instead of adding a manual
of_node_put(child) at the probe_quit_interface error label, so the
reference on the current child node is released automatically on
every exit path from the loop, including the early goto on a
netcp_create_interface() failure. child is never used outside the
loop, so the now-unused outer child declaration is dropped along
with it; no extra of_node_get() is needed.

v2: Rework around for_each_available_child_of_node_scoped() instead
    of the manual of_node_put(child) from v1, per Andrew Lunn's
    review.
