Benny Halevy ed9122a84e time_window_compaction_strategy: get_reshaping_job: restrict sort of multi_window vector to its size ...

Currently the function calls boost::partial_sort with a middle
iterator that might be out of bound and cause undefined behavior.

Check the vector size, and do a partial sort only if its longer
than `max_sstables`, otherwise sort the whole vector.
