[PATCH 1/2] cryptodev: move dh type from xform to dh op

[Arek Kusztal <arkadiuszx.kusztal@intel.com>]

Operation type (PUBLIC_KEY_GENERATION, SHARED_SECRET) should
be free to choose for any operation. One xform/session should
be enough to perform both DH operations, if this is xform
member, session needs to be created twice for the same group,
similar problem would be observed in sessionless case.
Additionally it will help extending DH to support Elliptic Curves.
