Lioncash 947d364dba gpu_thread: Remove unused dma_pusher class member variable from ThreadManager
The pusher instance is only ever used in the constructor of the
ThreadManager for creating the thread that the ThreadManager instance
contains. Aside from that, the member is unused, so it can be removed.
