The compressdev enqueue call will return the number of ops that
it was able to accept. By design this will always be 1 for our
implementation so check that to make sure.
If it is 0 then we queue the compression operation up and try
again after something is dequeued in the poller.
We will also queue if we can't get an mbuf or op from our pools.
