netfilter: xt_conntrack: fix inverted conntrack direction test
--ctdir ORIGINAL matches REPLY packets, and vv:
userspace sets "invert_flags &= ~XT_CONNTRACK_DIRECTION" in ORIGINAL
case.
Thus: (CTINFO2DIR(ctinfo) == IP_CT_DIR_ORIGINAL) ^
!!(info->invert_flags & XT_CONNTRACK_DIRECTION))
yields "1 ^ 0", which is true -> returns false.
Reproducer:
iptables -I OUTPUT 1 -p tcp --syn -m conntrack --ctdir ORIGINAL
