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
