IB/mlx5: Allow posting multi packet send WQEs if hardware supports
Set the field to allow posting multi packet send WQEs if hardware supports this feature. This doesn't mean the send WQEs will be for multi packet unless the send WQE was prepared according to multi packet send WQE format. User space shall use flag MLX5_IB_ALLOW_MPW to check if hardware supports MPW and allows MPW in SQ context.
