[PR] Fix idempotent table cache update handling [iotdb]

["Caideyipi (via GitHub)" <gi...@apache.org>]

Caideyipi opened a new pull request, #17959:
URL: https://github.com/apache/iotdb/pull/17959

   This PR makes DataNode table cache update handling idempotent when a commit or rollback update request is repeated or arrives after the pre-update entry has already been cleared. commitUpdateTable previously read the pre-update table and wrote it into a ConcurrentHashMap without checking for null, so a delayed duplicate commit could throw an NPE after the entry was already handled. The change treats missing or cleared pre-update entries as already handled and makes removeTableFromPreUpdateMap tolerant of absent entries. Tests: mvn -pl iotdb-core/datanode -am -Dtest=DataNodeTableCacheTest -DfailIfNoTests=false -Dsurefire.failIfNoSpecifiedTests=false -Dspotless.skip=true -Dcheckstyle.skip=true test -DskipITs; mvn -pl iotdb-core/datanode -DskipTests -DskipITs spotless:check checkstyle:check.
