fix(fmath.h): One more fast_exp fix (AcademySoftwareFoundation#4275)

In PR AcademySoftwareFoundation#4268, I accidentally changed the clause addressing what is seemingly a bug with older MSVS. I'm just putting things back the way they were. It's not a new change, just restoring this line closer to the way it was about 3 commits back. Signed-off-by: Larry Gritz <[email protected]>
