[ofw] Patch: swap the src and dst gids to allow mad replies to return

[Tzachi Dar]

I don't think that the lids are being treated in a similar way, but there is a very similar code on the function spl_qp_alias_recv_cb (al_smi.c line 3325)

	if( p_mad_request->grh_valid )
	{
		cl_memcpy( &av_attr.grh, p_mad_request->p_grh1, sizeof( ib_grh_t ) );
		av_attr.grh.src_gid	 = p_mad_request->p_grh1->dest_gid;
		av_attr.grh.dest_gid = p_mad_request->p_grh1->src_gid;
		av_attr.grh_valid = TRUE;
	}

Thanks
Tzachi
