Kevin Hao 3fb65f6bc7 net: pktgen: Use wait_event_freezable_timeout() for freezable kthread ...

A freezable kernel thread can enter frozen state during freezing by
either calling try_to_freeze() or using wait_event_freezable() and its
variants. So for the following snippet of code in a kernel thread loop:
  wait_event_interruptible_timeout();
  try_to_freeze();

We can change it to a simple wait_event_freezable_timeout() and then
eliminate a function call.
