net: Fix useless comment reference loop.
include/linux/skbuff.h says:
/* These elements must be at the end, see alloc_skb() for details. */
net/core/skbuff.c says:
* See comment in sk_buff definition, just before the 'tail' member
This patch contains my guess as to the actual reason rather than a
dead comment reference loop.
