usb: musb_debugfs: don't use the struct file private_data field with seq_files
seq_files use the private_data field of a file struct for storing a seq_file structure, data should be stored in seq_file's own private field (e.g. file->private_data->private) Otherwise seq_release() will free the private data when the file is closed.
