[PATCH net-next] docs/conf.py: add function attribute '__fix_address' to conf.py

[menglong8 . dong]

From: Menglong Dong <imagedong@xxxxxxxxxxx>

Stephen Rothwell report that the function attribute '__fix_address'
causes a warning when create html docs with the command:

  make htmldocs

Therefor, add this attribute to c_id_attributes in Documentation/conf.py
to clean this warning.

BTW, I'm not able to reproduce this warning (both ubuntu and centos are
tested). I will appreciate it if anyone can have a test for this
commit.
