audit: wait_for_auditd rework for readability
We had some craziness with signed to unsigned long casting which appears wholely unnecessary. Just use signed long. Even though 2 values of the math equation are unsigned longs the result is expected to be a signed long. So why keep casting the result to signed long? Just make it signed long and use it. We also remove the needless "timeout" variable. We already have the stack "sleep_time" variable. Just use that... Signed-off-by: Eric Paris <eparis@redhat.com>
