commit 20f9de9b5f704cec55df92406a50bcbcfca96acd

libdwfl: Sanity check partial core file data reads.
There were two issues when reading note data from a core file.
We didn't check if the data we already had in a buffer was big
enough. And if we did get the data, we should check if we got
everything, or just a part of the data.
