Pablo Neira Ayuso a206bcb3b0 netfilter: xt_TCPOPTSTRIP: fix possible off by one access 
Fix a possible off by one access since optlen()
touches opt[offset+1] unsafely when i == tcp_hdrlen(skb) - 1.

This patch replaces tcp_hdrlen() by the local variable tcp_hdrlen
that stores the TCP header length, to save some cycles.
