[PATCH 4.9 0/1] selinux: drop super_block backpointer from superblock_security_struct

[Alexander Grund <theflamefire89@gmail.com>]

This backports a commit from upstream which I would consider a cleanup
as well as a (minor) performance fix due to less memory being used and
avoiding an unneccessary pointer dereferencing, i.e. the change
from `sbsec->sb->s_root` to `sb->s_root`.

However as it changes the `superblock_security_struct` please check if
this violates any API/ABI stability requirements which I'm not aware of.
