[PATCH 5.13 242/300] net/mlx5: Remove all auxiliary devices at the unregister event

[ Upstream commit 8e7e2e8ed0e251138926838b7933f8eb6dd56b12 ]

The call to mlx5_unregister_device() means that mlx5_core driver is
removed. In such scenario, we need to disregard all other flags like
attach/detach and forcibly remove all auxiliary devices.

Fixes: a5ae8fc9058e ("net/mlx5e: Don't create devices during unload flow")
