s4-provision: Fix the problem of DnsProperty values not being set correctly

DnsProperty can have empty 'data' member. To parse Dnsproperty with
empty data, dnsp.idl has a hack as follows:

  [switch_is(wDataLength?id:DSPROPERTY_ZONE_EMPTY)] dnsPropertyData data;

This implies, to set 'data' value, wDataLength has to be set to a non-zero
value first.
