daemon/logger: read the length header correctly
Before this change, if Decode() couldn't read a log record fully,
the subsequent invocation of Decode() would read the record's non-header part
as a header and cause a huge heap allocation.

This change prevents such a case by having the intermediate buffer in
the decoder struct.

Fixes #42125.
