debugfs: Correct the 'debugfs_create_str' docs
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.
