avcodec/cbs_jpeg: Try to move the read entity to one side in a test 
The checked entity should be alone on one side of the check, this avoids
complex considerations of overflows.
This fixes a issue of bad style in our code and a coverity issue.

Fixes: CID1439654 Untrusted pointer read

  • libavutil includes hashers, decompressors and miscellaneous utility functions.
  • libavfilter provides means to alter decoded audio and video through a directed graph of connected filters.
  • libavdevice provides an abstraction to access capture and playback devices.
  • libswresample implements audio mixing and resampling routines.
  • libswscale implements color conversion and scaling routines.

Tools

  • ffmpeg is a command line toolbox to manipulate, convert and stream multimedia content.
  • ffplay is a minimalistic multimedia player.
  • ffprobe is a simple analysis tool to inspect multimedia content.
  • Additional small tools such as aviocat, ismindex and qt-faststart.
