Liang Ma 96c343868d distributor: fix livelock on flush 
The Distributor autotest can lock if ran enough times. Worker and
distributor threads get into a livelock situation waiting on each
other.

To repeat:
`while sudo sh -c "echo 'distributor_autotest' |
		./build/app/test/dpdk-test"; do :; done`

The root cause is where we are flushing on exit, and do not wait for
all worker packets to be returned before exiting.
Add a delay on flush so that all worker packets are returned before
completing the flush.
