[vulkan] Correct the semantics of QFV_NextOffset

Browse source 
I'm not at all sure what I was thinking when I designed it, but I
certainly designed it wrong (to the point of being fairly useless). It
turns out memory requirements are already aligned in size (so just
multiplying is fine), and what I really wanted was to get the next
offset aligned to the given requirements.
