Refactor sdlz to use name instead of pointer to name

Browse Source 
Right now dns_sdlzlookup has a slight difference from other dbnode
implementations in that it stores a pointer to a dns name instead of
the dns name itself.

This commit harmonizes dns_sdlzlookup with other dbnode
implementations, facilitating further refactoring.
