rt2x00: Don't kick TX queue after each frame
TX queues shouldn't be kicked after each frame that is put into the queue. This could cause problems during RTS and CTS-to-self as well as with fragmentation. In all those cases you want all frames to be send out in a single burst. Off course we shouldn't let the queue fill up entirely, thus we introduce a 10% threshold which, when reached, will force the frames to be send out regardless of the frame. In addition we should prevent queues to become full in such a way that the tx() handler can fail. Instead of stopping the queue when it is full, we should stop it when it is below the threshold.
