Joe Hattori b15b92daf6 net: mdiobus: fix an OF node reference leak ...

[ Upstream commit 572af9f284 ]

fwnode_find_mii_timestamper() calls of_parse_phandle_with_fixed_args()
but does not decrement the refcount of the obtained OF node. Add an
of_node_put() call before returning from the function.

This bug was detected by an experimental static analysis tool that I am
developing.
