MDEV-16866 InnoDB fails to start upon crash recovery with "[ERROR] InnoDB: Redo log crypto: failed to decrypt log block"bb-10.1-MDEV-16866
- If InnoDB encounters garbage or incomplete written log block during
recovery then don't throw the error. Treat it as end of the log.
- This kind of incomplete or empty block can be result of killing
InnoDB when writing the redo log.
