Update git submodules

* Update docs/submodules/samplevnf from branch 'master'
  - Merge "Fix latency accuracy and dumping latencies to file"
  - Fix latency accuracy and dumping latencies to file
    
    - Also changed lat_info.tx_packet_index to uint64_t,
      so also did it for task_lat.prev_tx_packet_index and n_loss.
    - Adjusted format strings accordingly, and fixed some other formats.
    - Adjusted overflow increment to 2^32 (i.e. UINT32_MAX + 1).
    - Replaced hard-coded 64 with ACCURACY_BUFFER_SIZE (still hard-coded
      in handle_gen.c).
