Robert Hancock 6bb9e376c2 net: dsa: microchip: Don't try to read stats for unused ports 
If some of the switch ports were not listed in the device tree, due to
being unused, the ksz_mib_read_work function ended up accessing a NULL
dp->slave pointer and causing an oops. Skip checking statistics for any
unused ports.
