Gawain: fix for last commit

Follow-up to 3bc6b831d82724578fc8150d863b54f334db2bf4

Initial code was getting the number of ShaderInterfaces that could fit between two pointers (which makes no sense). I really meant number of bytes.

Surprised it worked on Mac, glad I tested on Windows before bed  :D
