net/mlx5: add packet type index for TCP ack

According to CQE format:
- l4_hdr_type:
     0 - None
     1 - TCP header was present in the packet
     2 - UDP header was present in the packet
     3 - TCP header was present in the packet with Empty
         TCP ACK indication. (TCP packet <ACK> flag is set,
         and packet carries no data)
     4 - TCP header was present in the packet with TCP ACK indication.
         (TCP packet <ACK> flag is set, and packet carries data).

A packet should be identified as TCP packet if l4_hdr_type is 1, 3 or 4.
Add corresponding idx of TCP ACK to ptype table.
