Commit eb6f43fb4ce4 "[kernel] list: fix order of arguments for
hlist_add_after(_rcu)" (upstream 1d023284c31a) introduced new hlist_add_behind
function, which fixes unnatural argument order used in hlist_add_after
function. In order to force switch to the new interface and avoid confusion,
function name has been changed.

Backport change: Add macro shim for hlist_add_behind() which calls
hlist_add_after() with reversed argument order.
