The stuck queue detection mechanism allows to detect queues that are stuck. For sleeping clients, a queue may rightfully be stuck: if a poor client implementation stays asleep for more than 10s, then we don't want to trigger recovery flows because of that client. In order to cope with this, I added a mechanism that monitors the state of the client: when a client goes to sleep, the timer of his queues is frozen. When he wakes up, the timer is reset to the right value so that if a client was awake for more than 10s and the queues are stuck, only then, the recovery flow will kick in. This is valid only on non-shared queues: A-MPDU queues. There was a bug in case we Tx to a sleeping client that has an empty A-MPDU queue: the timer was armed to now + 10s. This is bad, but pretty harmless. The problem is that when the client wakes up, the timer is modified to be now + remainder. But remainder is 0 since the queue was empty when that client went to sleep... Fix this by checking the state of the client before playing with the timer when we add a packet to an empty queue.
