pktgen: better scheduler friendliness

Browse source

Previous update did not resched in inner loop causing watchdogs.
Rewrite inner loop to:
  * account for delays better with less clock calls
  * more accurate timing of delay:
    - only delay if packet was successfully sent
    - if delay is 100ns and it takes 10ns to build packet then
      account for that
  * use wait_event_interruptible_timeout rather than open coding it.
