Marko Mäkelä 5e93fe11cb MDEV-37677: Inconsistent flush_list after InnoDB recovery 
In commit bea4adcb5a (MDEV-35225)
we inadvertently introduced a race condition. Another thread
may invoke buf_page_t::write_complete() between the time
log_sort_flush_list() inserted the block to the list for sorting,
and the time it would apply the sorted list back to buf_pool.flush_list.
In this case, log_sort_flush_list() would neither add the block to
buf_pool.flush_list nor clear the buf_page_t::oldest_modification_
so that it would correctly indicate whether the block is in the list.

log_sort_flush_list(): Simplify the logic, and always add the entire
sorted list to the buf_pool.flush_list, even if they had been written
back during the time we were copying or sorting.

This fixes an anomaly where a subsequent
buf_pool_t::insert_into_flush_list() would end up incrementing
buf_pool.flush_list.count by one too much.

Thanks to Daniel Black for providing an "rr replay" trace of a
failure.
