Continuing the fun of trying to find exactly the delay that is sufficient to ensure that the page directory is fully loaded between context switches, move the extra flush added in commit70b73f9ac1("drm/i915/ringbuffer: Delay after invalidating gen6+ xcs") to just after we flush the pd. Entirely based on the empirical data of running failing tests in a loop until we survive a day (before the mtbf is 10-30 minutes).

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
