Subject: [PATCH] net: stmmac: Fix incorrect memcpy source memory

The memcpy() currently copies mdio_bus_data into new_bus->irq, which
makes no sense, since the mdio_bus_data structure contains more than
just irqs. The code was likely supposed to copy mdio_bus_data->irqs
into the new_bus->irq instead, so fix this.
