net/ipv4: Move call_fib_entry_notifiers up for new routes Move call to call_fib_entry_notifiers for new IPv4 routes to right before the call to fib_insert_alias. At this point the only remaining failure path is memory allocations in fib_insert_node. Handle that very unlikely failure with a call to call_fib_entry_notifiers to tell drivers about it. At this point notifier handlers can decide the fate of the new route with a clean path to delete the potential new entry if the notifier returns non-0.
