Add FIXME for non-zero security attributes

[Pavel Roskin <proski@gnu.org>]

Hello!

winemine compiled and run under Windows 2000 doesn't save scores.  It
turns out RegCreateKeyEx() fails because it gets invalid security
attributes.  It's an input argument, but winemine doesn't initialize it
and doesn't use it afterwards.  Also, the last argument "disp" is not
used.

This error would have been found earlier if we had a FIXME for non-zero
security attributes.

The attached patch adds FIXME to all functions ignoring "sa" in
dlls/advapi32/registry.c except RegSaveKeyA() that uses RegSaveKeyW().

Also, programs/winemine/main.c is simplified to replace unused pointers
with NULL in SaveBoard().
