    wined3d: Try harder to reuse the current context.

Reverting the patch, it works as expected. In other words, on startup, it shows
the brand logo (white background), warning messages (black background) and
title screen.
This issue is similar to Bug 47479, but it still occurs on Wine 4.18.

Step to reproduce:
 1. Click [体験版DL] in http://www.getchu.com/soft.phtml?id=1057414
    In short,
    % wget --referer='http://www.getchu.com/soft.phtml?id=1057414' \
      http://trial.getchu.com/D100/1057414/youka_trial.zip
 2. verify SHA1 value, i.e. sha1sum youka_trial.zip should be
    e8f5efb74d9ee0a6c1041d23657b10aa5356990c.
 2. unzip youka_trial.zip
 3. cd youka_trial
 4. LANG=ja_JP.UTF-8 wine youka_taiken.exe
