audit: remove unused actx param from audit_rule_match
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 03d37d25e0f9 ("LSM/Audit: Introduce generic
Audit LSM hooks") but appears to have never been used.
Remove it.
