ABI changes are not allowed until 20.11, however, this change is an API change
(not ABI) for an experimental API which can be allowed.
Could you please move this to relevant section.
@Hemant: any comments on this patch?

* [dpdk-dev] cryptodev: change raw data path dequeue API

This patch changes the experimental raw data path dequeue burst API.
Originally the API enforces the user to provide callback function
to get maximum dequeue count. This change gives the user one more
option to pass directly the expected dequeue count.
