ACL: Fix next_table_index classifiers consistancy
Fixed consistancy between the first classifier match and the
next_table_index classifier matches:
- CLASSIFY_ACTION_SET_METADATA was applied only for the first
classifier, but it was not applied for the other classifiers
- Actions should be performed only for input ACLs
- Payload should point at the IP header for output ACLs
