[B.A.T.M.A.N.] [PATCH] list: fix order of arguments for hlist_add_after(_rcu)

[Sven Eckelmann <sven@narfation.org>]

From: Ken Helias <kenhelias@firemail.de>

All other add functions for lists have the new item as first argument
and the position where it is added as second argument.  This was changed
for no good reason in this function and makes using it unnecessary
confusing.

The name was changed to hlist_add_behind() to cause unconverted code to
generate a compile error instead of using the wrong parameter order.
