Attention to serious bug CASSANDRA-15081

[Cameron Zemek <ca...@instaclustr.com>]

Have had multiple customer hit this CASSANDRA-15081 issue now, where
upgrading from older versions the sstables contain an unknown column (its
not present in the dropped_columns in the schema)

This bug is serious as reads return incorrect results and if you run scrub
it will drop the row. So hoping to bring it some attention to have the
issue resolved. Note I have included a patch that I think does not cause
any regressions elsewhere.

Regards,
Cameron

This looks like a dupe of CASSANDRA-15086, which has been committed and will be included in 3.0.19.
