tracing: Change tracing_pipe_fops() to rely on tracing_get_cpu()
commit 15544209cb0b5312e5220a9337a1fe61d1a1f2d9 upstream.
tracing_open_pipe() is racy, the memory inode->i_private points to
can be already freed.
Change debugfs_create_file("trace_pipe", data) callers to to pass
"data = tr", tracing_open_pipe() can use tracing_get_cpu().
