dlls/d3dx8/math.c -- simple fixup

[Gerald Pfeifer]

I found the following patch in my tree.  I do not recollect the original 
background, but while not a bug fix it simplifies things a bit and fixes 
indentation so I figured I'd pass it along.

Gerald

ChangeLog:
Reduce the scope of a variable and fix identation in D3DXMatrixInverse().
