Olivier Fourdan e196535abb dix: Clear device sprite after free in AttachDevice()
The code in AttachDevice() may free the dev->spriteInfo->sprite under
some circumstances and later call GetCurrentRootWindow() which uses
the same dev->spriteInfo->sprite.

While it seems unlikely that this is actually an issue, considering the
cases where one or the other get called, it still makes the code look
suspicious.

Make sure to clear set dev->spriteInfo->sprite to NULL  immediately
after it's freed to avoid any confusion, even if only to clarify the
code.
