Subject: [PATCH net 1/2] net/mlx4_en: Move filters cleanup to a proper location

From: Eugenia Emantayev <eugenia@...lanox.com>

Filters cleanup should be done once before destroying net device,
since filters list is contained in the private data.

Fixes: 1eb8c695bda9 ('net/mlx4_en: Add accelerated RFS support')
