Andrzej Jackowski c89d8c6566 cql3: prevent from empty option use in cf_statement::column_family()
Implementation of cf_statement::column_family() dereferences _cf_name
option without checking if the option is non-empty. On enterprise
branch, there is a safeguard that prevents from such an empty option
dereferencing. Although the current code on master seems to not call
columny_family() when _cf_name is empty, it is safer to introduce the
same workaround on master, to avoid any regression.

This change:
 - Prevent from empty option use in cf_statement::column_family()

Fixes: scylla-enterprise#5273

Closes scylladb/scylladb#23366
