[NETFILTER]: ctnetlink: return EEXIST instead of EINVAL for existing nat'ed conntracks

ctnetlink must return EEXIST for existing nat'ed conntracks instead of
EINVAL. Only return EINVAL if we try to update a conntrack with NAT
handlings (that is not allowed).

Decadence:libnetfilter_conntrack/utils# ./conntrack_create_nat
TEST: create conntrack (0)(Success)
Decadence:libnetfilter_conntrack/utils# ./conntrack_create_nat
TEST: create conntrack (-1)(Invalid argument)
