dlz_bind9: This fixes the problem with adding/deleting rdataset
Fix commit 169db333033b72b6f9ac1e7b23f0f2c151218c1f. This change
allowed for LDB records without dnsRecord attribute to exist to
prevent large number of deleted records.
This change fixes the handling of missing dnsRecord attribute
and correctly deleting dnsRecord attribute.
