[PATCH ghak81 RFC V2 3/5] audit: use inline function to get audit context

From: Richard Guy Briggs
Date: Sat May 12 2018 - 22:00:45 EST

Recognizing that the audit context is an internal audit value, use an
access function to retrieve the audit context pointer for the task
rather than reaching directly into the task struct to get it.
