net: dsa: Fix legacy probing
After commit 6d3c8c0dd88a ("net: dsa: Remove master_netdev and
use dst->cpu_dp->netdev") and a29342e73911 ("net: dsa: Associate
slave network device with CPU port") we would be seeing NULL pointer
dereferences when accessing dst->cpu_dp->netdev too early. In the legacy
code, we actually know early in advance the master network device, so
pass it down to the relevant functions.
Fixes: 6d3c8c0dd88a ("net: dsa: Remove master_netdev and use dst->cpu_dp->netdev")
Fixes: a29342e73911 ("net: dsa: Associate slave network device with CPU port")
