net: fib_notifier: propagate possible error during fib notifier registration
Unlike events for registered notifier, during the registration, the errors that happened for the block being registered are not propagated up to the caller. Make sure the error is propagated for FIB rules and entries. Signed-off-by: Jiri Pirko <jiri@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>
