nbp_reg_lookup()
Used to make sure an NBP entity does not exist before it is registered.
Returns 1 if the entity already exists,
0 if the entry does not exist
-1 for an error; e.g.no local zones exist
Does the right thing in multihoming mode, namely if the zone is
"*" (the default), it does the lookup in the default zone for
each interface.
