    no instance info cache update if instance deleted
    
    Avoid instance info cache update if the instance is deleted,
    as the deleted instance's info cache is already deleted in
    db layer and it will report InstanceInfoCacheNotFound
    exception and lead to a few exception logs in compute.
    
    Please note this is different to regular info cache and
    lead to InstanceInfoCacheNotFound exception, it's in the
    case when you first create the info cache after instance
    delete and InstanceInfo is also deleted.

Title:
  downgrade the exception log in update_instance_cache_with_nw_info

Status in OpenStack Compute (nova):
  Fix Released
Status in OpenStack Compute (nova) ocata series:
  Confirmed

Bug description:
  when compute node is down, nova api can accept delete action and delete the instance
  then during compute start up, periodic task will check whether the instance is deleted in api layer
   then performance actions

  saw those logs because actually the info case is already deleted so
  it's a valid case and should not report this exception ,just a log
  info should be fine
