Subject: [PATCH 4.19 04/34] apparmor: remove duplicate macro list_entry_is_head()

From: Andy Shevchenko <andriy.shevchenko@...ux.intel.com>

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.
