As part of the ShardingTest teardown, SERVER-88191 is adding new logic to drain inflight reshardCollection requests based on the response of the currentOp command. 

Test failures showed that the execution of such logic is causing a segfault while accessing a nullptr _metrics field: the problem seems to only affect the jstests/sharding/reshard_collection_retryability_with_uuid.js  and the jstests/sharding/reshard_collection_retry_after_failover.js tests when executed under the sharding_auto_bootstrap suite.

While the teardown validation has been disabled for the failing tests as a workaround, the objective of this ticket is to understand the root cause of the problem.
