net/mlx5: HWS: Reject unsupported remove-header action

Browse source

mlx5_cmd_hws_packet_reformat_alloc() handles
MLX5_REFORMAT_TYPE_REMOVE_HDR by looking up a matching HWS remove-header
action.

If mlx5_fs_get_action_remove_header_vlan() returns NULL, the code only
logs an error and continues. The function then returns success with a NULL
HWS action stored in the packet-reformat object.

Return an error when no matching remove-header action is available.

Fixes: aecd9d1020 ("net/mlx5: fs, add HWS packet reformat API function")
