arping should return when there is nothing left to do

[Hendrik Lönngren]

When using arping with a count and every probe has been answered promptly, arping waits until the next probe would be sent before printing the stats and returning. That is an unnecessary delay.

In the function recv_pack in arping.c, we have

290 if (quit_on_reply)
291 finish();

where it could be

290 if(quit_on_reply || count == 1 && received == sent)
291 finish();
