DDF: increase default value for safe_mode_delay to 4000ms
That is the same value that IMSM uses. The current default of 200ms seems to have been copied from the native MD meta data. That value appears to be much too low for DDF, given that writing the DDF meta data means that easily several MB worth of data need to be written to disk.
