Subject: [PATCH 7/8] netfilter: nfnetlink_osf: add missing enum in nfnetlink_osf uapi header

From: Fernando Fernandez Mancera <ffmancera@...eup.net>

xt_osf_window_size_options was originally part of
include/uapi/linux/netfilter/xt_osf.h, restore it.

Fixes: bfb15f2a95cb ("netfilter: extract Passive OS fingerprint infrastructure from xt_osf")
