needed to apply to the stable branch. If there were code changes for rebasing
(ie: not only metadata diffs), please double check that the rebase was
correctly done.

Subject: [PATCH] crypto/mvsam: fix session data reset

[ upstream commit 03e73e8572f112bd3714cd90c491a6570330189c ]

This patch fix wrong clear memory session pointer.

When call mrvl_crypto_pmd_sym_session_clear function,
it might cause the following error:
CRYPTODEV: set_sym_session_private_data() line 497:
Set private data for driver 1 not allowed

This fix set zeroes to mrvl_crypto_session pointer instead to
rte_cryptodev_sym_session pointer, and will verify that
rte_cryptodev_sym_session pointer will not lose data such as
nb_drivers.

Bugzilla ID: 646
Fixes: 8a61c83af2fa ("crypto/mrvl: add mrvl crypto driver")
