Subject: [PATCH ghak138 v2 2/4] audit: explicitly check audit_context->context enum value

Be explicit in checking the struct audit_context "context" member enum
value rather than assuming the order of context enum values.

Fixes: 12c5e81d3fd0 ("audit: prepare audit_context for use in calling contexts beyond syscalls")
