[ac] check fast path again in enqueueWaiter #16

Closed LK4D4 closed 5 years ago

Previously in some edge cases, it was possible that release happens between ac.mtx.Unlock and enqueueWaiter, and as a result, new waiter continues to wait for next Release even though there are resources for its ticket. In edge case when all resources released at that time - waiter never will be woken up.
