net: smsc911x: Fix bug where PHY interrupts are overwritten by 0
By default, mdiobus_alloc() sets the PHYs to polling mode, but a
pointer size memcpy means that a couple IRQs end up being overwritten
with a value of 0. This means that PHY_POLL is disabled and results
in unpredictable behavior depending on the PHY's location on the
MDIO bus. Remove that memcpy and the now unused phy_irq member to
force the SMSC911x PHYs into polling mode 100% of the time.
Fixes: e7f4dc3536a4 ("mdio: Move allocation of interrupts into core")
