Since commit 0394a63acf ("net: dsa: enable and disable all ports")
the dsa core disables all unused ports of a switch. In this case
disabling ports with numbers higher than QCA8K_NUM_PORTS causes that
some switch registers are overwritten with incorrect content.
To fix this, initialize the dsa_switch->num_ports with correct number
of ports.
