net/mlx5: fix GRE flow item translation for root table

Flow items translations for the root tables reuse DV code. However, the DV GRE item translation did not initialize the item mask for HWS template. Initialize the mask to fix GRE item translation for root tables when using HWS. Fixes: cd4ab74 ("net/mlx5: split flow item matcher and value translation") Cc: [email protected] Signed-off-by: Gregory Etelson <[email protected]> Acked-by: Suanming Mou <[email protected]>
