apparmor: Fix memory leak of rule on error exit path
Currently on the error exit path the allocated rule is not free'd
causing a memory leak. Fix this by calling aa_audit_rule_free().
Detected by CoverityScan, CID#1468966 ("Resource leaks")
Fixes: cb740f574c7b ("apparmor: modify audit rule support to support profile stacks")
