RDMA/mlx5: Remove ECE limitation from the RAW_PACKET QPs 

Like any other QP type, rely on FW for the RAW_PACKET QPs to decide if ECE
is supported or not. This fixes an inability to create RAW_PACKET QPs with
latest rdma-core with the ECE support.

Fixes: e383085c24 ("RDMA/mlx5: Set ECE options during QP create")
