raw: use explicit llseek file operations

The raw_fops may need to seek, so there should be an explicit reference to default_llseek. raw_ctl_fops does not contain a read or write method, so we use noop_llseek to ignore seeking requests without an error. Signed-off-by: Arnd Bergmann <[email protected]>
