This moves the bpf_sock_from_file definition into net/core/filter.c which only gets compiled with CONFIG_NET and also moves the helper proto usage next to other tracing helpers that are conditional on CONFIG_NET. This avoids ld: kernel/trace/bpf_trace.o: in function `bpf_sock_from_file': bpf_trace.c:(.text+0xe23): undefined reference to `sock_from_file' When compiling a kernel with BPF and without NET.

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.
