zebra: When we get an implicit or ack or full failure mark status

Browse Source 
When nl_batch_read_resp gets a full on failure -1 or an implicit
ack 0 from the kernel for a batch of code.  Let's immediately
mark all of those in the batch pass/fail as needed.  Instead
of having them marked else where.
