Chris Lu a549580e65 ec.balance: verify shard landed on destination before deleting the source (#9858 )

* ec.balance: verify shard(s) landed on the destination before deleting source

The EC balance task copied/mounted a shard to the destination and then
immediately unmounted+deleted it from the source, reporting success as soon
as the RPCs returned. A copy/mount can return OK while the shard isn't
actually registered/loadable on the destination, so deleting the source
then loses the shard (and the scanner re-issues the same move every cycle).

Add a verification step (VolumeEcShardsInfo via VerifyShardsAcrossServers,
the same check the EC encode task uses before deleting originals): if the
destination doesn't report every moved shard, fail the task and keep the
source so the move is retried instead of losing data.

* address review: use comma-ok when reading destination shard inventory
