Print the nested stats attribute containing timestamping statistics when
the --show-time-stamping flag is used.

  [root@...ary-eater-vm-01 linux-ethtool-ts]# ./tools/net/ynl/ethtool.py --show-time-stamping mlx5_1
  Time stamping parameters for mlx5_1:
  Capabilities:
    hardware-transmit
    hardware-receive
    hardware-raw-clock
  PTP Hardware Clock: 0
  Hardware Transmit Timestamp Modes:
    off
    on
  Hardware Receive Filter Modes:
    none
    all
  Statistics:
    tx-pkts: 8
    tx-lost: 0
