[5/6] cryptodev: remove old get session size functions

  Removed rte_cryptodev_get_header_session_size
and rte_cryptodev_get_private_session_size functions,
as they have been substituted with functions
specific for symmetric operations, with _sym_ word
after "rte_cryptodev_".

rte_cryptodev_get_private_session_size is not removed in this patch. I 
think you missed it in your patch.

[Shally] I missed this before. I think this implementation either should change to use nb_drivers which support symmetric or else I am not seeing a need for separate sym specific API for header_size since it will always be same for both sym and asym.

Thanks
Shally

Right Akhil, thanks for spotting this. Will fix in next version.

The implementation is already using nb_drivers to calculate the size, right?
Anyway, I understand that the way asymmetric sessions are done, the API
will be the same, but this could change in the future and since we have already deprecated the
generic function (get_header_session_size), I think we should continue and have both _sym and _asym_ functions.

Thanks,
Pablo

[Shally] I meant change it to nb_sym_drivers, where nb_sym_drivers = number of drivers that have symmetric capability

Ok, I see now. Well, this will overcomplicate things, rte_cryptodev_allocate_driver
would need to be changed to two functions,
one for symmetric and another for asymmetric, causing an API breakage.
I think as long as the session creation/initialization functions check if a PMD supports
symmetric and/or asymmetric, we should be OK.

We might need some changes in the current symmetric implementation to peform those checks
and in the new asymmetric implementation.

Thanks,
Pablo
