[PATCH] swsusp: remove wrong code from data_free

Browse source 
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.
