PM / hibernate: Deletion of an unnecessary check before the function call « vfree »

Classé dans Coccinelle, Linux

Author: Markus Elfring <elfring@users.sourceforge.net>

The vfree() function performs also input parameter validation. Thus the test
around the call is not needed.

This issue was detected by using the Coccinelle software.
