### What problem does this PR solve? cloud heavy sc job will retry the whole alter tasks when encounter `KV_TXN_CONFLICT_RETRY_EXCEEDED_MAX_TIMES` error in `commit_tablet_job`(#46748). We should remove stop token(#48399) in MS for the sc job if it fails in `commit_tablet_job`, otherwise the later retries may fail to regsiter stop token(because the first stop token won't expire in `config::lease_compaction_interval_seconds * 4=80s`) and the schema change job will fail. ``` I20250318 15:40:15.851157 7677 task_worker_pool.cpp:423] successfully submit
