Check SPTE writable invariants when setting SPTEs rather than in spte_can_locklessly_be_made_writable(). By the time KVM checks spte_can_locklessly_be_made_writable(), the SPTE has long been since corrupted. Note that these invariants only apply to shadow-present leaf SPTEs (i.e. not to MMIO SPTEs, non-leaf SPTEs, etc.). Add a comment explaining the restriction and only instrument the code paths that set shadow-present leaf SPTEs. To account for access tracking, also check the SPTE writable invariants when marking an SPTE as an access track SPTE. This also lets us remove a redundant WARN from mark_spte_for_access_track().

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.
