Subject: net: stmmac: Fix incorrect memcpy source memory

From: Marek Vasut <marex@denx.de>

[ Upstream commit 643d60bf575daaba93c1ac0d0e1c4b1d4ded1f75 ]

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.
