[PATCH] swsusp: remove wrong code from data_free
The following patch removes some wrong code from the data_free() function in swsusp. This function could only be called if there's an error while writing the suspend image to swap, so it is not triggered easily. However, if triggered, it would probably corrupt some memory.
