Improve FMLP queue management.wip-fmlp-dequeue
The next owner of a FMLP-protected resource is dequeued from the FMLP FIFO queue by unlock() (when the resource is freed by the previous owner) instead of performing the dequeue by the next owner immediately after it has been woken up. This simplifies the code a little bit and also reduces potential spinlock contention.
