[PATCH 06/20] IB/ipoib: drop useless LIST_HEAD

[Julia Lawall]

Drop LIST_HEAD where the variable it declares is never used.

Commit 31c02e215700 ("IPoIB: Avoid using stale last_send counter
when reaping AHs") removed the uses, but not the declaration.

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

// <smpl>
@@
identifier x;
@@
- LIST_HEAD(x);
  ... when != x
// </smpl>

Fixes: 31c02e215700 ("IPoIB: Avoid using stale last_send counter when reaping AHs")
