[PATCH 1/2] slimbus: qcom-ngd-ctrl: Add of_node_put() before return

[Srinivas Kandagatla]

From: Nishka Dasgupta <nishkadg.li...@gmail.com>

Each iteration of for_each_available_child_of_node puts the previous
node, but in the case of a return from the middle of the loop, there is
no put, thus causing a memory leak. Hence add an of_node_put before the
return in two places.
Issue found with Coccinelle.
