BUG 9014: Remove unnecessary Log statements for evpn/subnetroute

1.Modified error logs to debug logs in necessary places
from evpn rt2 code, especially which hits for non-evpn scenarios.

2. This cannot find portOp Error was earlier relevant
where race conditions existed between interface-state
event southbound and subnet-port openstack configuraiton from
northbound.   Later we divided handling the subnetroute
creation into two batches to address the race condition
properly in [1].

As a result with [1] being merged, the error statement for
portOp is not required anymore and so this fix removes that
error statement.
