kernel: netfilter: synproxy: refresh tcphdr after skb_ensure_writable

A flaw was found in the Linux kernel's netfilter synproxy module. When handling TCP timestamp options, a stale pointer can be used after memory reallocation. This can result in memory corruption, where data is written to a freed memory area, or lead to packets being sent with an incorrect checksu...
