    RTSP/SDP: Fix parsing error for H264:sprop-parameter-sets
    
    Rework the method verifying  if there are more data in packed attribute
    New version checks if there are any non-zero bits after the current bit in the
    packet. If it sees some non-zero bits - that means there is some data in the
    packet. If there are zero bits only - that means there is no more data in the
    packet.
    Changes affect RTSP/SDP dissector and they are specific for
    SDP media attribute (a) fmtp/sprop-parameter-sets for H264 protocol
