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);
//
