In raft_sys_table_storage::store_snapshot_descriptor(), the condition
preserve_log_entries > snap.idx
*both* relies on implicit conversion of the tagged integer type "index_t"
to the underlying "uint64_t", *and* is a logic bug, as reported at
<https://github.com/scylladb/scylladb/issues/20080>.
Ticket#20080 explains that this condition always evaluates to false in
practice, and that the "else" branch handles all cases correctly anyway.
For now, wean the buggy expression off the disappearing
tagged-to-untaggged conversion.
