staging: lustre: obdclass: obd_config: remove unneeded null test before free
Kfree can cope with a null argument, so drop null tests.
The semantic patch that identifies this issue is as follows:
(http://coccinelle.lip6.fr/)
// <smpl>
@@ expression ptr; @@
- if (ptr != NULL)
kfree(ptr);
// </smpl>
The first part of the patch introduces new labels to avoid unnecessary
calls to kfree. In addition, lprof->lp_md is always null in the cleanup
code at the end of the function, so that kfree is just dropped.
