gdi32: Protect against short sized LOGPALETTE in CreatePalette.

[Dan Kegel]

Hi,
your patch uses IsBadReadPtr(), but that function
is deprecated in favor of using an exception handler.
See
http://www.winehq.org/pipermail/wine-devel/2006-April/046560.html
Here's an example (sorry it's a messy one, it's just the first one
google found):

Please try recoding using that approach.

If you have trouble getting this patch in, you might want to
file a bug at http://bugs.winehq.org for your problem and link
to your patch; that will record the problem so somebody else
can pick it up later.
