staging: lustre: ldlm: ldlm_resource: 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>
