ima: Have the LSM free its audit rule
Ask the LSM to free its audit rule rather than directly calling kfree().
Both AppArmor and SELinux do additional work in their audit_rule_free()
hooks. Fix memory leaks by allowing the LSMs to perform necessary work.
Fixes: b16942455193 ("ima: use the lsm policy update notifier")
