IB/mlx4: Make sure inline data segments don't cross a 64 byte boundary
Inline data segments in send WQEs are not allowed to cross a 64 byte boundary. We use inline data segments to hold the UD headers for MLX QPs (QP0 and QP1). A send with GRH on QP1 will have a UD header that is too big to fit in a single inline data segment without crossing a 64 byte boundary, so split the header into two inline data segments.
