Staging: wilc1000: Remove null check before kfree

kfree on NULL pointer is a no-op.

This patch uses the following semantic patch to find such an instance
where NULL check is present before kfree.

// <smpl>
@@ expression E; @@
- if (E != NULL) { kfree(E); }
+ kfree(E);
@@ expression E; @@
- if (E != NULL) { kfree(E); E = NULL; }
+ kfree(E);
+ E = NULL;
// </smpl>smpl>
