drm-shim: Return -EINVAL instead of abort()ing on unknown ioctls.
I had this as abort() in my original implementation since I was doing
drm-shim and my kernel driver in parallel based around using a SW
simulator, and I wanted to always update both, but it means that people's
new feature detection code can easily end up breaing their drm-shim
shader-db runs (such as intel's kernel_has_dynamic_config_support()
checking for -ENOENT instead of -EINVAL for a feature, which showed up on
my personal runner but not fd.o's for reasons I'm unclear on).
