Staging: wilc1000: linux_wlan: Remove NULL check before kfree



kfree on NULL pointer is a no-op.

The semantic patch used -

// <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>
