mutate_MV usually calls send_to_endpoint() to push view update to remote
view replicas. This function gets passed a statistics object,
service::storage_proxy_stats::write_stats and, in particular, updates
its "writes" statistic which counts the number of ongoing writes.
In the case that the paired view replica happens to be the *same* node,
we avoid calling send_to_endpoint() and call mutate_locally() instead.
That function does not take a write_stats object, so the "writes" statistic
doesn't get incremented for the duration of the write. So we should do
this explicitly.
