[PATCH 4/6] leds: gpio: fix and simplify reading property "label"

[Heiner Kallweit]

Checking for the presence of the property first isn't strictly needed
as we can react on the return code of fwnode_property_read_string.
Also, even if the presence of a property "label" was checked,
reading a string value for it theoretically still can fail and
this case isn't handled.
