net/mlx5: Return EOPNOTSUPP when failing to get steering name-space
[ Upstream commit eff596da48784316ccb83bef82bc1213b512d5e0 ]
When we fail to retrieve a hardware steering name-space, the returned error
code should say that this operation is not supported. Align the various
places in the driver where this call is made to this convention.
Also, make sure to warn when we fail to retrieve a SW (ANCHOR) name-space.
