s3: libsmb: Finally change _internal_resolve_name() to return a talloc'ed ip_service array.

The wrapper internal_resolve_name() is now functionaly identical to _internal_resolve_name()
so we can remove it and rename _internal_resolve_name() back to internal_resolve_name().

dup_ip_service_array() is now no longer used, so comment it
out as it's a staic function.
