As suggested by Cong, introduce a tracepoint for all ->sk_data_ready()
callback implementations.  For example:

<...>
  ksoftirqd/0-16  [000] ..s..  99.784482: sk_data_ready: family=10 protocol=58 func=sock_def_readable
  ksoftirqd/0-16  [000] ..s..  99.784819: sk_data_ready: family=10 protocol=58 func=sock_def_readable
<...>

changes since v3:
  - Avoid using __func__ everywhere (Leon Romanovsky)
  - No need to trace iscsi_target_sk_data_ready() (Leon Romanovsky)

I meant no need both trace point and debug print and suggested to remove
debug print.

Thanks
