MDEV-26516: WSREP: Record locking is disabled in this thread, but the table being modified

Browse source 
We periodically observe assertion failures in the mtr tests,
specifically in the /storage/innobase/row/row0ins.cc file,
following a WSREP error. The error message is: 'WSREP: record
locking is disabled in this thread, but the table being modified
is not mysql/wsrep_streaming_log: mysql/innodb_table_stats.'"
This issue seems to occur because, upon opening the table,
innodb_stats_auto_recalc may trigger, which Galera does not
anticipate. This commit should fix this bug.
