qlocale_win: Simplify and explain month-name format lookup

Browse Source 
Retain the given month number and simply subtract one from it in the
one place it's used (once the two array dereferencs are unified). That
makes it clear that the off-by-one numbering is just down to our
arrays, not some weired quirk of the MS API. Simplify a condition by
inverting it: compare to LongFormat instead of ||-ing comparisons to
the other two members of the enum.
