net/mlx5: Avoid using xso.real_dev unnecessarily

Browse source

[ Upstream commit d79444e8c3 ]

xso.real_dev is the active device of an offloaded xfrm state and is
managed by bonding. As such, it's subject to change when states are
migrated to a new device. Using it in places other than
offloading/unoffloading the states is risky.

This commit saves the device into the driver-specific struct
mlx5e_ipsec_sa_entry and switches mlx5e_ipsec_init_macs() and
mlx5e_ipsec_netevent_event() to make use of it.

Additionally, mlx5e_xfrm_update_stats() used xso.real_dev to validate
that correct net locks are held. But in a bonding config, the net of the
master device is the same as the underlying devices, and the net is
already a local var, so use that instead.

The only remaining references to xso.real_dev are now in the
.xdo_dev_state_add() / .xdo_dev_state_delete() path.
