Input: adc-joystick - use device_for_each_child_node_scoped()

Switch to the _scoped() version introduced in commit 365130fd47
("device property: Introduce device_for_each_child_node_scoped()")
to remove the need for manual calling of fwnode_handle_put() in the
paths where the code exits the loop early.

In this case the err_fwnode_put label was no longer necessary and the
error code is returned directly.
