selftests/bpf: Fix erroneous bitmask operation
xdp_synproxy_kern.c is a BPF program that generates SYN cookies on
allowed TCP ports and sends SYNACKs to clients, accelerating synproxy
iptables module.
Fix the bitmask operation when checking the status of an existing
conntrack entry within tcp_lookup() function. Do not AND with the bit
position number, but with the bitmask value to check whether the entry
found has the IPS_CONFIRMED flag set.
