What problem does this PR solve?

When I add a new ddl job type: recover table, I found this bug.
The old version TiDB owner will think the new type job as Invalid. Then the old tidb crash because runtime: goroutine stack exceeds 1000000000-byte limit fatal error: stack overflow
Cause of the problem:

err = errInvalidDDLJob.GenWithStack("invalid ddl job: %v", job)
job.Error = toTError(err)
job.String() // stack overflow

There is a circular references in job and job.Error.

What is changed and how it works?

err = errInvalidDDLJob.GenWithStack("invalid ddl job type: %v", job.Type)
