   ### What changes were proposed in this pull request?
   Previously, the snapshot for rollback was created outside the lock, which 
could lead to inconsistent state and race conditions in concurrent scenarios.
   This change ensures the snapshot is always created while holding the lock, 
preventing data corruption and ensuring reliable transaction rollback.
   
   ### Why are the changes needed?
   
   (Please clarify why the changes are needed. For instance,
     1. If you propose a new API, clarify the use case for a new API.
     2. If you fix a bug, describe the bug.)
   
   Fix: #7977
   
   ### Does this PR introduce _any_ user-facing change?
   No
   
   ### How was this patch tested?
   With UTs added earlier
