Handle errors inflating notifications (and their icons).

On an inflation error, the StatusBarService cleans up, removes / doesn't add
the views, and calls into the StatusBarManagerService, which tells the
NotificationManagerService to remove the notification.

That then calls all the way back into the StatusBarService, but I think being
extra careful is okay.  Throughout the status bar, it's all keyed off of the
IBinder key, so if the app comes in with a good notification while we're
cleaning up, we won't lose the new notification or anything like that.
