net: dsa: qca8k: Initialize the switch with correct number of ports 



Since commit 0394a63a ("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.
