kmod-setup: don't print warning on -ENOSYS

-ENOSYS is returned from kmod_module_probe_insert_module() if a module isn't
available, not -ENOENT. Don't spit out a warning in that case unless the
warn_if_unavailable flag is set.

Also factor out the condition into an own variable for better readability.
