test: assert EC shard identity and empty-view, not just counts, in lifecycle
Follow-up to the multi-disk EC lifecycle tests (#10721), addressing review
feedback.
The phase checks compared shard counts. A reconcile that put a shard on the
wrong disk, or loaded a different shard than the file on disk, keeps 6/5/3
right while corrupting the mapping. Compare the exact registered shard set per
disk at every phase instead, via a shared assertRegistered helper. The
cross-disk mount phase now also pins that shard 0 landed on disk2 with the
existing shards, not merely that it is findable.
The sidecar-disk-lost scenario only logged the registered view, so a change
that registered shards without reachable sidecars would pass despite the
documented expectation that the view stays empty. It now asserts
countRegistered == 0: a registered-but-unreadable shard is worse than an
unregistered one, because the master advertises it.
The first store's closer is now deferred as a closure the moment the store is
created, so a Fatalf in an early phase no longer leaks it and its
notification-drainer goroutine; the closure reads the reassigned variable so it
also covers the post-restart store.
