[dpdk-dev] [PATCH v2 07/11] cryptodev: remove driver id from session

[Pablo de Lara]

From: Slawomir Mrozowicz <slawomirx.mrozowicz at intel.com>

Since crypto session will not be attached to a specific
device or driver, the field driver_id is not required
anymore (only used to check that a session was being
handled by the right device).
