MDEV-8851 innodb.innodb_information_schema fails sporadically
The column INFORMATION_SCHEMA.INNODB_LOCKS.LOCK_DATA
would report NULL when the page that contains the locked
record does not reside in the buffer pool.
Pages may be evicted from the buffer pool due to some background
activity, such as the purge of transaction history loading
undo log pages to the buffer pool. The regression tests intentionally
run with a small buffer pool size setting.
To prevent the intermittent test failures, we will filter out the
contents of the LOCK_DATA column from the output.
