Ticket 47355 - dse.ldif doesn't replicate update to nsslapd-sasl-mapping-fallback

Bug Description: Setting the feature on and off through ldapmodify can leave the dse.ldif
                 in an inconsistent state.

Fix Description: Using a Slapi_Counter is not necessary, and it caused issues.  Set the config
                 type back to integer.
