This patch prints out TEST_COUNT for every tests in script pm_netlink.sh.

The output looks like:

  1 defaults addr list                        [ OK ]
  2 simple add/get addr                       [ OK ]
  3 dump addrs                                [ OK ]
  4 simple del addr                           [ OK ]
  5 dump addrs after del                      [ OK ]
  6 duplicate addr                            [ OK ]
  7 id addr increment                         [ OK ]
  8 hard addr limit                           [ OK ]
  9 above hard addr limit                     [ OK ]

Having test counters helps to quickly identify issues when looking at a
long list of output logs and results.
