Sergey Vojtovich b40b3720cb MDEV-21348 - column compression memory leak ...

The Storage-Engine Independent Column Compression does not call
deflateEnd() when deflate() does not return Z_STREAM_END.

This for instance happens when the data is already (externally)
compressed and deflate() needs more space than the original data.

This patch is based on contribution by Martijn Broenland.
