debugfs: fix create mutex racy fops and private data commit d3a3b0adad0865c12e39b712ca89efbd0a3a0dbc upstream. Setting fops and private data outside of the mutex at debugfs file creation introduces a race where the files can be opened with the wrong file operations and private data. It is easy to trigger with a process waiting on file creation notification.
