  Discard transport stream packets with invalid adaptation field length

See ISO/IEC 13818-1 : 2000 (E). 2.4.3.5 Semantic definition of fields in adaptation field
Invalid adaptation field length can cause array bound violations when processing the
adaptation field content and when array boundary checking for std::array is enabled.

  Log Message:
  -----------
  Remove superfluous VERBOSE_LEVEL_CHECK macro in adaptation field size check

This check is not needed because LOG is a macro that starts with the VERBOSE_LEVEL_CHECK
macro and there are no computations before LOG is called.
