avcodec/h264: Set CORRUPT flag on output frames that are not fully recovered

Browse Source 
In the merge commit 78265fcfee this behaviour
was broken and the CORRUPT flag would never ever be set on a frame. However
the flag on the AVCodecContext was taken into account properly, including
AV_CODEC_FLAG2_SHOW_ALL.

The reason for this was that the recovered field of the next output picture
was always set to TRUE whenever one of the two AVCodecContext flags was set,
which made it impossible to detect later, before outputting, if the frame was
really recovered or not. Now don't set it to TRUE unless the frame is really
recovered and check the AVCodecContext flags right before outputting.
