commit 2019554f9656 introduces implementation of icmp{,v6}_ndo_send in
include/linux/icmp{,v6}.h in case of NF_NAT is enabled. Now these
functions are defined twice in wireguard. Fix this by hiding code if
NF_NAT is set (reverse condition as in icmp*.h)

Hi,

sorry, please ignore this
wireguard was included with 5.6, my 5.4 uses external wireguard

regards Frank
