APPARMOR: Fix memory leak of alloc_namespace()

Browse Source 
policy->name is a substring of policy->hname, if prefix is not NULL, it will
allocted strlen(prefix) + strlen(name) + 3 bytes to policy->hname in policy_init().
use kzfree(ns->base.name) will casue memory leak if alloc_namespace() failed.
