net/mlx5: fs, add unused destination type
When the caller doesn't pass a destination fs_core will create a unused
rule just so a context can be returned. This unused rule
is zeroed out and its type is 0 which can be mixed up with
MLX5_FLOW_DESTINATION_TYPE_VPORT.
Create a dedicated type to differentiate between the two
named MLX5_FLOW_DESTINATION_TYPE_NONE.
