staging: lustre: libcfs: linux: remove unneeded null test before free
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/)
// <smpl>
@@ expression ptr; @@
- if (ptr != NULL) {
kfree(ptr);
ptr = NULL;
- }
// </smpl>
