When parsing diagnosis information of Unix sockets the current code uses the wrong offset (
sizeofSocket) for determining the start of the attached parameters.As a result, returned attributes might be scrambled or missing. More severely, the code might panic if no or only a small number of attributes are available as e.g. in influxdata/telegraf#16527
This PR uses the correct
sizeofUnixSocketoffset to fix the issue.
