9p-trans_fd: fix and clean up module init/exit paths
trans_fd leaked p9_mux_wq on module unload. Fix it. While at it, collapse p9_mux_global_init() into p9_trans_fd_init(). It's easier to follow this way and the global poll_tasks array is about to removed anyway. Signed-off-by: Tejun Heo <tj@kernel.org> Signed-off-by: Eric Van Hensbergen <ericvh@gmail.com>
