Fixed wxFileDialog::MSWOnInitDone and wxFileDialog::MSWOnSelChange never being called.

A condition was checking for the wrong CDN_XXX message range resulting in CDN_INITDONE and CDN_SELCHANGE no longer being processed. Broken since r75937 (branches/WX_3_0_BRANCH/) and r75941 (trunk/).

See #16003.
