struct nf_conn contains a "struct nf_conntrack ct_general" member and struct net contains a "struct netns_ct ct" member which are both only defined in CONFIG_NF_CONNTRACK is enabled. These members are used in a number of inline functions defined in other header-files. Added preprocessor checks to make sure the headers will compile if CONFIG_NF_CONNTRACK is disabled.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
