Al Viro f765b134c0 new_sync_write(): discard ->ki_pos unless the return value is positive 
That allows ->write_iter() instances much more convenient life wrt
iocb->ki_pos (and fixes several filesystems with borderline POSIX
violations when zero-length write succeeds and changes the current
position).
