IMPALA-11637: Add DCHECK in AdmissionController::UpdateExecGroupMetric

There has been occurrences where an impala backend crash and lead to
metric admission-controller.executor-group.num-queries-executing.*
goes negative. While we still investigating the exact scenario leading
into this negative metric issue, this patch add a DCHECK in
AdmissionController::UpdateExecGroupMetric to ensure that such case
does not happen in regular nightly tests.

Testing:
- Run and pass exhaustive test.
