Prevent double panic when handling incremental fingerprint mismatch
When an incremental fingerprint mismatch occurs, we debug-print our `DepNode` and query result. Unfortunately, the debug printing process may cause us to run additional queries, which can result in a re-entrant fingerprint mismatch error. To avoid a double panic, this commit adds a thread-local variable to detect re-entrant calls.
