When ovsdb-server reads a database file that is corrupted at the transaction level (that is, the transaction is valid JSON and has the correct SHA-1 hash, but it does not describe a valid database transaction), then ovsdb-server should truncate it and overwrite it by valid transactions. However, until now, it didn't. Instead, it would keep the invalid transaction and possibly every transaction in the database file (depending on in what way the transaction was invalid), which would just cause the same trouble again the next time the database was read. This fixes the problem. An invalid transaction will be deleted from the database file at the first write to the database. Bug #5144. Bug #5149.
