In case host->packed_min will be set to a value bigger than 2 you will
loose all the requests that were added to the packed list. If you want to
support dynamic number of min packed requests you need to move the packed
list preparation to queue.c where you can issue the fetched requests one
after another, when (reqs < card->host->packed_min).
