mm/zswap: delete unnecessary check before calling free_percpu()
Author: Markus Elfring <elfring@users.sourceforge.net>
free_percpu() tests whether its argument is NULL and then returns
immediately. Thus the test around the call is not needed.
This issue was detected by using the Coccinelle software.
