Javier Carrasco e78d04d364 leds: flash: mt6360: Fix device_for_each_child_node() refcounting in error paths 
commit 73b03b2773 upstream.

The device_for_each_child_node() macro requires explicit calls to
fwnode_handle_put() upon early exits to avoid memory leaks, and in
this case the error paths are handled after jumping to
'out_flash_realease', which misses that required call to
to decrement the refcount of the child node.

A more elegant and robust solution is using the scoped variant of the
loop, which automatically handles such early exits.

Fix the child node refcounting in the error paths by using
device_for_each_child_node_scoped().
