Ticket 47636 - Error log levels not displayed correctly

Bug Description:  Searching for nsslapd-errorlog-level returns an
                  unexpected value (the level plus 16384).

Fix Description:  This is a regression from the first fix for this
                  ticket.  The fix is to only adjust the level zero,
                  to its full default value of 16384.
