This queue is used for sleeping in kernel and it have to be per-net since we don't want to wake any other waiters except in out network nemespace. BTW, move wq to per-net data is easy. But some way to handle upcall timeouts have to be provided. On message destroy in case of timeout, tasks, waiting for message to be delivered, should be awakened. Thus, some data required to located the right wait queue. Chosen solution replaces rpc_pipe_msg object with new introduced bl_pipe_msg object, containing rpc_pipe_msg and proper wq.
