## What changes were proposed in this pull request? Saw this warning when datanode disk was nearly full: ``` 2025-12-15 10:37:20,903 WARN [166c5ca8-343e-46ed-b619-84ac193e0069-ChunkReader-215]-org.apache.hadoop.hdds.fs.CachingSpaceUsageSource: Attempted to decrement available space to a negative value. Current: 0, Decrement: 1048576, Source: /ipdr_ozone31/hadoop-ozone/datanode/data ``` Prior to this message, there were many failed writes. Perhaps it needs to increment the value when the write fails. The fix adds rollback logic in `KeyValueHandler.handleWriteChunk()` that tracks when a chunk write succeeds and increments the `usedSpace` counter. If any subsequent operation fails, the exception handler calls `volume.decrementUsedSpace()` to restore the counter. ## What is the link to the Apache JIRA [HDDS-14183](https://issues.apache.org/jira/browse/HDDS-14183) ## How was this patch tested?
