Joe Hattori aa9e573145 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.
