Subject: [PATCH 5.4 15/90] net/mlx5e: Remove dependency in IPsec initialization flows

From: Huy Nguyen <huyn@...dia.com>

[ Upstream commit 8ad893e516a77209a1818a2072d2027d87db809f ]

Currently, IPsec feature is disabled because mlx5e_build_nic_netdev
is required to be called after mlx5e_ipsec_init. This requirement is
invalid as mlx5e_build_nic_netdev and mlx5e_ipsec_init initialize
independent resources.

Remove ipsec pointer check in mlx5e_build_nic_netdev so that the
two functions can be called at any order.

Fixes: 547eede070eb ("net/mlx5e: IPSec, Innova IPSec offload infrastructure")
