net: dsa: use cpu_switch instead of ds[0]
Now that the DSA Ethernet switches are true Linux devices, the CPU switch is not necessarily the first one. If its address is higher than the second switch on the same MDIO bus, its index will be 1, not 0. Avoid any confusion by using dst->cpu_switch instead of dst->ds[0].
