do fail on weakhash/loop earlier in acquire
The bugreport shows a segfault caused by the code not doing the correct magical dance to remove an item from inside a queue in all cases. We could try hard to fix this, but it is actually better and also easier to perform these checks (which cause instant failure) earlier so that they haven't entered queue(s) yet, which in return makes cleanup trivial. The result is that we actually end up failing "too early" as if we wouldn't be careful download errors would be logged before that process was even started. Not a problem for the acquire system, but likely to confuse users and programs alike if they see the download process producing errors before apt was technically allowed to do an acquire (it didn't, so no violation, but it looks like it to the untrained eye). Closes: 835195
