[dpdk-dev] [PATCH V2 2/4] crypto/mlx5: fix driver destroy before the configuration

[Raja Zidane <rzidane@nvidia.com>]

When calling device close, unset dek is called which destroys a hash list.
In case of error during dev probe, close is called when dek hlist is not
initialized.
Ensure non null list destroy.
