Subject: [net-next 03/15] ixgbe: drop null test before destroy functions

From: Julia Lawall <julia.lawall@...6.fr>

Remove unneeded NULL test.

The semantic patch that makes this change is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
@@ expression x; @@
-if (x != NULL)
  \(kmem_cache_destroy\|mempool_destroy\|dma_pool_destroy\)(x);
// </smpl>
