    libsframe: bugfix in flip_sframe
    
    A previous commit bdb0d62281a to make flip_fde version aware added a new
    argument for passing the remaning buffer size to the involved functions.
    Fix the passed value to the intended.
    
    libsframe/
            * sframe.c (flip_sframe): Correct the passed value of buf size.
