commit 9801ca279ad37f72f71234fa81722afd95a3f997 upstream.

Strangely I hadn't had noticed the existence of the list_entry_is_head()
in apparmor code when added the same one in the list.h. Luckily it's
fully identical and didn't break builds. In any case we don't need a
duplicate anymore, thus remove it from apparmor code.
