[dpdk-dev] [PATCH v4 06/12] cryptodev: remove device id from crypto session

[Pablo de Lara <pablo.de.lara.guarch@intel.com>]

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

Device id is necessary in the crypto session,
as it was only used for the functions that attach/detach
a session to a queue pair.

Since the session is not going to be attached to a device
anymore, this is field is no longer necessary.
