[PATCH] leds: pca9532: fix device_node_continue.cocci warnings

[Julia Lawall]

Device node iterators put the previous value of the index variable, so an
explicit put causes a double put.

I haven't looked at the context in detail, but given the rule, I assume
that there is an iterator, such as for_each_child_of_node, and these
iterators do a put on each iteration, so none is needed in the loop body.
