[PATCH] leds: max77705: fix fwnode reference leak in max77705_add_led()

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

In the RGB LED path of max77705_add_led(), the
fwnode_for_each_child_node() loop over the subled child nodes
returns directly on a max77705_parse_subled() failure without
releasing the reference held on the current child, since
fwnode_for_each_child_node() is not a scoped/cleanup-based
iterator and expects the caller to drop the reference itself on
any early exit from the loop body.

Call fwnode_handle_put() on the child fwnode before returning to
fix the leak.

Fixes: 3b6eaa3db567 ("leds: Use fwnode_for_each_child_node() instead")
