Description

Code correctness issue, no repro.

Comment at https://github.com/yugabyte/yugabyte-db/blob/541b6495f0c129bc8d189d0da27ff68036f6fff4/src/yb/master/catalog_manager.cc#L11632 says we should expect the list to be in tablet id sorted order. But the call from https://github.com/yugabyte/yugabyte-db/blob/541b6495f0c129bc8d189d0da27ff68036f6fff4/src/yb/master/catalog_manager_ext.cc#L3307 does not ensure this. This can potentially lead to a deadlock.

Ideally, we can assert this while acquiring locks in debug mode so that such cases are reported by unit tests.
