Add missed call to onReadRequestFinish() when read request rejected (#3482)
Fixes: https://github.com/apache/bookkeeper/issues/2945
### Motivation
When a read request is rejected due to the limit on the number of reads that can be enqueued, we need to decrement the metric for `bookkeeper_server_READ_ENTRY_IN_PROGRESS` and release the `readsSemaphore`, if it is not null.
### Changes
* Call `onReadRequestFinish()` for failures in the V2 and V3 request processing logic.
### Observation
It looks like the V2 responses for this kind of failure are not throttled, even when `throttleReadResponses` is true. We could call `read.sendReadReqResponse(` to enable this throttling. I didn't change it here because there might be a reason we're not throttling these small responses.
