MIPS: Octeon: add missing of_node_put()

BugLink: https://bugs.launchpad.net/bugs/1836117
[ 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.
