buf_flush_page(): Never wait for a page latch, even in checkpoint
flushing (flush_type == BUF_FLUSH_LIST), to prevent a hang of the
page cleaner threads when a large number of pages is latched.
In mysql/mysql-server@9542f3015b
it was claimed that such a hang only affects CREATE FULLTEXT INDEX.
Their fix was to retain buffer-fix but release exclusive latch
on non-leaf pages, and subsequently write to those pages while
they are not associated with the mini-transaction, which would
trip a debug assertion in the MariaDB version of
mtr_t::memo_modify_page() and cause potential corruption
when using the default MariaDB setting innodb_log_optimize_ddl=OFF.
