Subject: [net-next 12/15] net/mlx5e: kTLS, Remove unnecessary per-callback completion

From: Tariq Toukan <tariqt@...dia.com>

Waiting on a completion object for each callback before cleaning up their
async contexts is not necessary, as this is already implied in the
mlx5_cmd_cleanup_async_ctx() API.
