Meyer Jacobs c4033dace0 scmstore: count contentstore batch errors more accurately
Summary:
Previously errors from `prefetch` weren't counted. With this change I move calculating the pending keys out of the `inner` method, making it easier to handle all batch error metrics from `?` calls right beside the existing `other_errors` call.

This is probably how I'll structure the other methods too, though it's still a little subtle - currently the batch errors only come from `prefetch`, but if batch errors were returned after the `drain` call (which always drains the vector, even if you don't consume the whole iterator), the second `pending.len()` call could incorrectly report 0. To address this, I could separate out the "single key fetching" part of the method, or just let it be understood that you should repeatedly call `pop` in such cases.
