[PATCH] ioemu : sdl without OpenGl fix

[<sygus@cat-lan.com>]

Hi,

Here is a little patch for a bug introduced recently in the SDL ioemu
rendering, in case we disable OpenGl. Without this patch, the SDL window
just stoppped when there were a call to ds->dpy_setdata, because the
pointer was not set.

Kind regards,
Frédéric Guihéry
