Bugfix: Limit log length in case of corrupted sample storage:
In case of a sample address reset the header would have a smaler end address as the start address. As result the length becomes very long and download e.g. via Subsurface, would seem to hang. To solve this the number of sample bytes in this use case has been limited. Tested with subsurface only. After change dowload of logs is possible again. Nevertheless the sampledata will be lost.
Minor change: "header" was used as global as well as as local variable => changed name for global variant to gheader.
