drisw: Avoid crashing when swrast_loader == NULL

This is a blanket fix for all the segfaults in `drisw_init_screen()`
when `swrast_loader` is NULL, since 1de7c86bc1. A similar more targeted
fix for vmwgfx can be found in f3b8d7da46 ("egl: never select swrast
for vmwgfx"). We can safely return NULL because the caller
`driCreateNewScreen3` handles NULL, as does its own callers.

As this is currently the top crasher of gnome-shell since Ubuntu
upgraded to Mesa 25 and it seems to be coming from multiple different
drivers still, we want a universal fix to at least stop the crash
reports. People can figure out which drivers still need tweaking in
`dri2_load_driver` or elsewhere later.

Fixes: 1de7c86bc1 ("dri: pass through a type enum for creating screen instead of driver_extensions")
