Improved error reporting in mysqlbinlog when used with --flashback.

Previously, the error message:
"Error row length: 0"

was too vague and did not provide sufficient debugging information.

This patch enhances the error message by clearly indicating:

  • failure during row event parsing
  • row length
  • expected condition (valid row data)

This helps users better diagnose issues when processing binlog events.
