net: allwinner: emac: Add missing free_irq
commit b91113282bf44df46aba374a0b8f88a75bfd4b3f 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.
