net: dsa: microchip: remove ksz_port:on variable
The only place where this variable would be set to false is the
ksz8_config_cpu_port() function. But it is done in a bogus way:
for (i = 0; i < dev->phy_port_cnt; i++) {
if (i == dev->phy_port_cnt) <--- will be never executed.
break;
p->on = 1;
So, we never have a situation where p->on = 0. In this case, we can just
remove it.
