Aaron Sierra fc5d1829f9 NTB: transport: Try harder to alloc an aligned MW buffer
Be a little wasteful if the (likely CMA) message window buffer is not
suitably aligned after our first attempt; allocate a buffer twice as big
as we need and manually align our MW buffer within it.

This was needed on Intel Broadwell DE platforms with intel_iommu=off
