mdio: mux: fix device_node_continue.cocci warnings
[ Upstream commit 8c977f5a856a7276450ddf3a7b57b4a8815b63f9 ]
Device node iterators put the previous value of the index variable, so an
explicit put causes a double put.
In particular, of_mdiobus_register can fail before doing anything
interesting, so one could view it as a no-op from the reference count
point of view.
