crypto/mvsam: fix session data reset

[ upstream commit 03e73e8 ]

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: 8a61c83 ("crypto/mrvl: add mrvl crypto driver")
