sna: Avoid selecting gen9 backend for future gen
Cannonlake, then Icelake introduce new instruction formats and state
command, and require a new render backend to be written. Avoid selecting
the gen9 backend as this will hang!
Closes: https://gitlab.freedesktop.org/drm/intel/-/issues/1864
Fixes: 3d5a1238af6a ("sna: Restore blt fallback backend")
