lm32: milkymist-tmu2: fix another integer overflow
Don't truncate the multiplication and do a 64 bit one instead
because the result is stored in a 64 bit variable.
This fixes a similar coverity warning to commit 237a8650d640,
in a similar way, and is the other half of the fix for
coverity CID 1167561.
