Subject: [PATCH 4.19 107/422] net/mlx5: Fix atomic_mode enum values

From: Moni Shoua <monis@...lanox.com>

[ Upstream commit aa7e80b220f3a543eefbe4b7e2c5d2b73e2e2ef7 ]

The field atomic_mode is 4 bits wide and therefore can hold values
from 0x0 to 0xf. Remove the unnecessary 20 bit shift that made the values
be incorrect. While that, remove unused enum values.

Fixes: 57cda166bbe0 ("net/mlx5: Add DCT command interface")
