X11DRV: fix fbconfig regression

[Roderick Colenbrander]

Hi,

During my opengl rewrite I caused a regression (bug 6205) in the opengl code. There's a piece of code which checks the GLX version and based on the GLX version certain GLX functions are loaded. In the rewrite some code got changed and I forgot to take those changes into account.

There's this check:
     if ((!WineGLInfo.glxDirect && !strcmp("1.2", WineGLInfo.glxServerVersion)) ||
         (WineGLInfo.glxDirect && !strcmp("1.2", WineGLInfo.glxClientVersion)))

When the if-statement is 'true' the GLX version is 1.2 and we should check for the GLX_SGIX_fbconfig extension. Else the version is 1.3 or newer and then certain functions are standard GLX functionality.

By accident I switched the contents of the if and else blocks. This code swaps it and fixed bug 6205.

Regards,
Roderick Colenbrander
