[PATCH net-next V2 02/13] net/mlx5: Detach auxiliary devices on attach failure during load

[Tariq Toukan <tariqt@nvidia.com>]

From: Dragos Tatulea <dtatulea@nvidia.com>

The device attach phase fails in mlx5_load_one_devl_locked() when
the first device fails to attach. The error path doesn't detach
the remaining devices that successfully attached.

Fix the above condition by properly calling detach on the error
path.

This issue was found during code inspection and was not reproduced.
Hence it doesn't deserve a Fixes tag.
