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.
