netfilter: nft_set_pipapo: clamp maximum map bucket size to INT_MAX
In the Linux kernel, the following vulnerability has been resolved: netfilter: nft_set_pipapo: clamp maximum map bucket size to INT_MAX Otherwise, it is possible to hit WARN_ON_ONCE in __kvmalloc_node_noprof() when resizing hashtable because __GFP_NOWARN is unset. Similar to: b541ba7d1f5a ("netfilter: conntrack: clamp maximum hashtable size to INT_MAX")
