net: dsa: pass CPU port fixed PHY to .port_disable

Browse source 
While adding the logic for DSA to register a fixed-link PHY for the CPU
port, I forgot to pass it to the .port_disable method too, just
.port_enable.

Bug had no impact for felix_switch.c, due to the phy argument not being
used, but ksz9477.c does use it => NULL pointer dereference.

Fixes: fc054d563b ("net: Introduce DSA class for Ethernet switches")
