glx: fix non-dri build

glXGetDriverConfig parameters do not provide a context to dynamically
check for the presence of the function, so the dispatcher directly calls
glXGetDriverConfig, but in non-dri builds dri_glx.c didn't provide
glXGetDriverConfig.

This change make it just return NULL in that case.
