[NETFILTER] ctnetlink: add one nesting level for TCP state
To keep consistency, the TCP private protocol information is nested
attributes under CTA_PROTOINFO_TCP. This way the sequence of attributes to
access the TCP state information looks like here below:
CTA_PROTOINFO
CTA_PROTOINFO_TCP
CTA_PROTOINFO_TCP_STATE
instead of:
CTA_PROTOINFO
CTA_PROTOINFO_TCP_STATE
