RDMA/mlx5: Get ECE options from FW during create QP

Browse source 
Supported ECE options are returned from FW in the create_qp phase and zero
means that field is not valid. Such default value allows us to reuse
reserved field without worries about comp_mask.

Update create QP API to return ECE options.
