In the HFileBlock class, the log printing fspread/fsread cost time unit should be milliseconds

protected HFileBlock readBlockDataInternal(FSDataInputStream is, long offset, long onDiskSizeWithHeaderL, boolean pread, boolean verifyChecksum, boolean updateMetrics, boolean intoHeap) throws IOException {
  ...
  long startTime = EnvironmentEdgeManager.currentTime();
  ...
  long duration = EnvironmentEdgeManager.currentTime() - startTime;
  if (updateMetrics) {
    HFile.updateReadLatency(duration, pread);
  }
  ...
  LOG.trace("Read {} in {} ns", hFileBlock, duration);
  ...
}
