During quit_workers function distributor's main core processes
some packets to wake up pending worker cores so they can quit.
As quit_workers acts also as a cleanup procedure for next test
case it should also collect these packets returned by workers'
handlers, so the cyclic buffer with returned packets
in distributor remains empty.
