tracing: Change tracing_stats_fops to rely on tracing_get_cpu()
commit 4d3435b8a4c3357695e09c5e7a3bf73a19fca5b0 upstream.
tracing_open_generic_tc() is racy, the memory inode->i_private
points to can be already freed.
1. Change one of its users, tracing_stats_fops, to use
tracing_*_generic_tr() instead.
2. Change trace_create_cpu_file("stats", data) to pass "data = tr".
3. Change tracing_stats_read() to use tracing_get_cpu().
