Fix signalling and waiting on semaphore from two queues (#2271)

Browse Source 
`semaphores_ooo_ops_cross_queue` uses two OOO command queues to run the
test. In one queue, a semaphore is signalled and the semahpore is waited
on in the other queue.

The CL specification requires the application to synchronize the queues
if objects are shared.
