net: allwinner: emac: Add missing free_irq

Browse source

commit b91113282b upstream.

If the mdio probe function fails in emac_open, the interrupt we just requested
isn't freed. If emac_open is called again, for example because we try to set up
the interface again, the kernel will oops because the interrupt wasn't properly
released.
