staging: lustre: obdecho: remove unneeded null test before free
Author: Julia Lawall <Julia.Lawall@lip6.fr>
Kfree can cope with a null argument, so drop null tests.
The semantic patch that makes this change is as follows:
(http://coccinelle.lip6.fr/)
//
@@ expression ptr; @@
- if (ptr != NULL)
kfree(ptr);
//
