notify: add NotiferWithReturn so notifier list can abort
notifier_list_notify() has no return value. This is fine when we just
want to invoke side-effects.
Sometimes it's useful for notifiers to produce a return value. This
allows notifiers to "veto" an operation and will be used by the block
layer before-write notifier.
