[PATCH v2] crypto: nx: nx-842-powernv: Add of_node_put() before return

Each iteration of for_each_compatible_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. Add an of_node_put before the return.
Issue found with Coccinelle.

- Fixed commit message to match the loop in question.
