Peter Dillinger e8f997ca59 Update comment on max_valid_backups_to_open (#6105)
Summary:
To reflect changes in PR https://github.com/facebook/rocksdb/issues/6072

This comment also implies that a seemingly valid use-case for
max_valid_backups_to_open is flawed: even if you only want to add a new
backup without trying to delete, you might need to clean up after a
backup creation that never finished. To clean up properly requires
opening all backups to get proper ref counts on shared files.
Pull Request resolved: https://github.com/facebook/rocksdb/pull/6105

Test Plan: code comment only
