leds: lp50xx: Put fwnode in error case during ->probe()

Browse Source 
[ Upstream commit f1e1d532da7e6ef355528a22fb97d9a8fbf76c4e ]

fwnode_for_each_child_node() bumps a reference counting of a returned variable.
We have to balance it whenever we return to the caller.

OTOH, the successful iteration will drop reference count under the hood, no need
to do it twice.
