    linuxkpi: Update posittion after copy in `seq_read()`
    
    `seq_read()` is usually called in a loop because the destination buffer
    might be smaller than the source. The caller relies on the updated
    position to read what is next.
    
    We also use `memcpy()` instead of `strscpy()` because we don't need to
    append a NUL character.
