The old Nouveau GL driver has no support for GPUs after Ada. Instead,
users will always get NVK+Zink on Hopper+. Right now, if the user sets
NOUVEAU_USE_ZINK=false, the loader will return "nouveau" and EGL/GLX
will try to load that, fail, and then fall back to Zink. With this
patch, we instead print a warning message and then load Zink anyway.
Backport-to: 25.2
