Pull selinux updates from Paul Moore:

 - Ensure that both IPv4 and IPv6 connections are properly initialized

   While we always properly initialized IPv4 connections early in their
   life, we missed the necessary IPv6 change when we were adding IPv6
   support.

 - Annotate the SELinux inode revalidation function to quiet KCSAN

   KCSAN correctly identifies a race in __inode_security_revalidate()
   when we check to see if an inode's SELinux has been properly
   initialized. While KCSAN is correct, it is an intentional choice made
   for performance reasons; if necessary, we check the state a second
   time, this time with a lock held, before initializing the inode's
   state.

 - Code cleanups, simplification, etc.

   A handful of individual patches to simplify some SELinux kernel
   logic, improve return code granularity via ERR_PTR(), follow the
   guidance on using KMEM_CACHE(), and correct some minor style
   problems.
