[sms] Fix two bugs regarding 7 bit coding... 

- Fix the length (almost)
    - Move the second part by 8 - b_off
      e.g. with (ba) 0x62 0x61 the first bit of
      0x61 goes to the highest on the first byte and
      the second word contains 0x110000...

    - The simple test case is almost passed... just a missing
      character at the end.
