UPSTREAM: netfilter: ipset: add the missing IP_SET_HASH_WITH_NET0 macro for ip_set_hash_netportnet.c

commit 050d91c03b28ca479df13dfb02bcd2c60dd6a878 upstream.

The missing IP_SET_HASH_WITH_NET0 macro in ip_set_hash_netportnet can
lead to the use of wrong `CIDR_POS(c)` for calculating array offsets,
which can lead to integer underflow. As a result, it leads to slab
out-of-bound access.
This patch adds back the IP_SET_HASH_WITH_NET0 macro to
ip_set_hash_netportnet to address the issue.

Bug: 302199939
Fixes: 886503f3 ("netfilter: ipset: actually allow allowable CIDR 0 in hash:net,port,net")
