net/mlx5e: Fix wrong application of the LRO state
Driver caches packet merge type in mlx5e_params instance which must be
in perfect sync with the netdev_feature's bit.
Prior to this patch, in certain conditions (*) LRO state was set in
mlx5e_params, while netdev_feature's bit was off. Causing the LRO to
be applied on the RQs (HW level).
(*) This can happen only on profile init (mlx5e_build_nic_params()),
when RQ expect non-linear SKB and PCI is fast enough in comparison to
link width.
Solution: remove setting of packet merge type from
mlx5e_build_nic_params() as netdev features are not updated.
