    Detect when v2 services get disabled after HUP.
    
    During service configuration, rend_service_prune_list_impl_() sets
    rend_service_staging_list to NULL, which blocked pruning after a HUP.
    
    This patch initializes rend_service_staging_list when needed, so that HUP can
    detect disabled onion services.
    
    Fixes bug #25761.
