[PATCH] net/mlx5: fix raw encap validation

[Gregory Etelson]

In SWS, `mlx5_flow_dv_validate_action_raw_encap_decap` is called for
flow action. The action validation checks for both size and data
parameters.

In HWS, `mlx5_flow_dv_validate_action_raw_encap_decap` is called for
the action template and validates the action mask.

The patch separates encap validation in
`mlx5_flow_dv_validate_action_raw_encap_decap` for SWS and HWS cases.

Fixes: cbfa4ed03913 ("net/mlx5: update flow actions validation before template creation")
