Prevent unnecessary dismissal retries. We stop retrying a dismissal if:
1. The response from the server indicates that retrying is hopeless;
2. We kept retrying for 1 day.
BUG=164227
TEST=Disconnect network and dismiss a notification. Observe the console output. Make sure that dismissal attempts continue for 1 day and then stop. (Of course, you don't have to run this test on every Canary release :))
