iptables: restore reap functionality to recent module

The reap functionality appears to have been accidentally disabled by
commit 74ded7257e5da5e309844d386290f24ae91950a6 to iptables.git, see:

  git://git.netfilter.org/iptables.git



and subsequently in iptables 1.4.15 and later.  This adds a patch to
restore reap functionality for recent_opts_v1.
