**Expected behavior**

LogPrint BCLog::BENCH should print useful timing metrics

**Actual behavior**

`Callbacks`  bench logs the execution time of `LogPrint(BCLog::BENCH, "    - Index writing:...`  function call

```
    int64_t nTime5 = GetTimeMicros(); nTimeIndex += nTime5 - nTime4;
    LogPrint(BCLog::BENCH, "    - Index writing: %.2fms [%.2fs (%.2fms/blk)]\n", MILLI * (nTime5 - nTime4), nTimeIndex * MICRO, nTimeIndex * MILLI / nBlocksTotal);

    int64_t nTime6 = GetTimeMicros(); nTimeCallbacks += nTime6 - nTime5;
    LogPrint(BCLog::BENCH, "    - Callbacks: %.2fms [%.2fs (%.2fms/blk)]\n", MILLI * (nTime6 - nTime5), nTimeCallbacks * MICRO, nTimeCallbacks * MILLI / nBlocksTotal);
```

Callbacks bench was added in this commit: https://github.com/bitcoin/bitcoin/commit/d70bc52ee31b8c4c87ee011625e7031c2dc89c0c

Since then functions between  ` Index writing:` and `Callbacks:`  were moved. 
Now Callbacks bench isn't recording anything of value. 
Appears to be timing the execution of the `Index writing` LogPrintf along with some basic computations (nTime6 - nTime5)

**To reproduce**

Start a node with initial block download

```
bitcoind -debug=bench | grep Callbacks:
```

You'll see the times recorded are within a small bounded range.
On my system it was between 30-50 microseconds
