[Mesa-dev] radv: Handle failing to create .cache dir. BISECTED - This one is broken

[Dieter Nützel]

Hello Bas,

here is something lost/broken.
Part-of: 
<https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/5181>

If you have NO
~/.cache/radv_builtin_shaders64

it wouldn't be (re)created any longer.

Reverting #cd61f5234d2 solved it.

Thanks,
Dieter
