netfilter: add more values to enum ip_conntrack_info

Following error is raised (and other similar ones) :

net/ipv4/netfilter/nf_nat_standalone.c: In function ‘nf_nat_fn’:
net/ipv4/netfilter/nf_nat_standalone.c:119:2: warning: case value ‘4’
not in enumerated type ‘enum ip_conntrack_info’

gcc barfs on adding two enum values and getting a not enumerated
result :

case IP_CT_RELATED+IP_CT_IS_REPLY:

Add missing enum values
