Multisite: Ensure the {$network_id}:notoptions array is set in cache in get_network_option().

Browse Source 
Prior to this change, the `{$network_id}:notoptions` cache would only be fetched, but not set, unless the actual database lookup would be unsuccessful. This enhancement slightly improves performance by preventing unnecessary external object cache lookups if one is used.

Fixes #43506.
