acl_lib: remove unused dualstack code from acl library

JIRA: SAMPLEVNF-14

The simultaneous IPV4 and IPV6 traffic is not required/supported.
The IPv4 and IPv6 separation is done to avoid multiple checks between
v4 and v6 and to improve the throughput performance.

Remove this in-used/unsupported code from the acl library code.

- * Main packet processing function.

- *  - Burst lookup packets in the IPv6 ACL Rule Table.
- *  - Lookup Action Table, perform actions.
- *  - Burst lookup Connection Tracking, if enabled.
- *  - Lookup MAC address.
- *  - Set bit mask.
- *  - Packets with bit mask set are forwarded
- *
- * @param p
- *  A pointer to the pipeline.
- * @param pkts
- *  A pointer to a burst of packets.
- * @param n_pkts
- *  Number of packets to process.
- * @param arg
- *  A pointer to pipeline specific data.
- *
- * @return
- *  0 on success, negative on error.
