vfs: make no_llseek the default
All file operations now have an explicit .llseek operation pointer, so we can change the default action for future code. This makes changes the default from default_llseek to no_llseek, which always returns -ESPIPE if a user tries to seek on a file without a .llseek operation. The name of the default_llseek function remains unchanged, if anyone thinks we should change it, please speak up.
