The audit_rule_match() struct audit_context *actx parameter is not used
by any in-tree consumers (selinux, apparmour, integrity, smack).

The audit context is an internal audit structure that should only be
accessed by audit accessor functions.

It was part of commit 03d37d25 ("LSM/Audit: Introduce generic
Audit LSM hooks") but appears to have never been used.

Remove it.
