Sergey Vojtovich a2bb9d2639 MDEV-7505 - Too large scale in DECIMAL dynamic column getter crashes mysqld ...

Server may crash if sanity checks of COLUMN_GET() fail.

COLUMN_GET() description generator expects parent CAST item, which may not have
been created due to failure of sanity checks. Then further attempt to report
an error may crash the server.

Fixed COLUMN_GET() description generator to handle such case.
