[PATCH] debugfs: Correct the 'debugfs_create_str' docs

From: Ivan Orlov
Date: Sun May 14 2023 - 13:24:09 EST

The documentation of the 'debugfs_create_str' says that the function
returns a pointer to a dentry created, or an ERR_PTR in case of error.
Actually, this is not true: this function doesn't return anything at all.
Correct the documentation correspondingly.
