fix MSVC-ARM internal compiler error by wrapping malloc

For some reason Microsoft CL compiler for ARM is unable to compile malloc when parameter is an expression. malloc(x * y) will cause internal compiler error, malloc(x) is however fine.

original code having bugs or deviating from

My guess is people who care about premultiply also care about color space.

Do the multiply inline, it should be a tad faster and not corrupt our data.
