Encoding: ACK/NACK: always encode with length field present

In most cases the length field was present and this field takes 7
bits of the maximum available 110 rest bits.
The length field was only removed when encoding huge bitmaps usually
only happen on lossy connections with packet lost.
However the cases without length field were encoded incorrect,
because all remaining bits must be used by the uncompressed bitmaps,
but the PCU violates this by encoding always the "release 5" bit.
Rather than fixing the encoding without length field, simply remove it
and always encode with length field. This also reduces the code
complexity.
