[PATCH 4.18 124/158] MIPS: Octeon: add missing of_node_put()

4.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Nicholas Mc Guire <redacted>

[ Upstream commit b1259519e618d479ede8a0db5474b3aff99f5056 ]

The call to of_find_node_by_name returns a node pointer with refcount
incremented thus it must be explicitly decremented here after the last
usage.
