net: add sk_fullsock() helper 



We have many places where we want to check if a socket is
not a timewait or request socket. Use a helper to avoid
hard coding this.

[Backport of net-next 1d0ab253872cdd3d8e7913f59c266c7fd01771d0]
[lorenzo@google.com: removed TCPF_NEW_SYN_RECV, and added a comment to add it back.]
