[krbdev.mit.edu #8331] potential memleak of pol_entry->name in populate_policy()

[Will Fiveash via RT]

In populate_policy() src/plugins/kdb/ldap/libkdb_ldap/ldap_pwd_policy.c:

    pol_entry->name = strdup(pol_name);

and later:

    if (st)
        goto cleanup;
    /*
     * We don't store the policy refcnt, because principals might be
maintained
     * outside of kadmin.  Instead, we will check for principal
references when
     * policies are deleted.
     */
    pol_entry->policy_refcnt = 0;

cleanup:
    return st;

So if st is non-zero then pol_entry->name will be leaked.
