[PATCH] MDEV-38811 crash in information_schema.table_constraints when --skip-grant-tables

acl_get_all3() wasn't expecting --skip-grant-tables

Multiple users reported Akonadi crashing with MariaDB 11.8.6. Downgrading to
11.8.5 fixed it. Reason most likely due to upstream regression as described
in detail in bug reports.
