[PULL 3/3] migration: clean up postcopy blocktime presentation

[Peter Xu <peterx@redhat.com>]

From: Bin Guo <guobin@linux.alibaba.com>

Small cleanups for the postcopy blocktime fine-grained tracking
feature:

* Remove a redundant memset() on latency_buckets after g_new0().
* Use singular "Latency" in the HMP label for postcopy non-vCPU
  latency, consistent with other single-value labels.
