UPSTREAM: locking/csd_lock: Remove added data from CSD lock debugging

The diagnostics added by this commit were extremely useful in one instance:

a5aabace ("locking/csd_lock: Add more data to CSD lock debugging")

However, they have not seen much action since, and there have been some
concerns expressed that the complexity is not worth the benefit.

Therefore, manually revert this commit, but leave a comment telling
people where to find these diagnostics.
