revert: 1320a4052ea1 ("audit: trigger accompanying records when no rules present")
Unfortunately the commit listed in the subject line above failed to ensure that the task's audit_context was properly initialized/set before enabling the "accompanying records". Depending on the situation, the resulting audit_context could have invalid values in some of it's fields which could cause a kernel panic/oops when the task/syscall exists and the audit records are generated. We will revisit the original patch, with the necessary fixes, in a future kernel but right now we just want to fix the kernel panic with the least amount of added risk.
