Mathieu Desnoyers 9f2813ec1f debugfs: fix create mutex racy fops and private data ...

commit d3a3b0adad 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.
