In commit6bb2a2af8b("drm/i915/gvt: Fix crash after request->hw_context change"), forgot to handle workload scan path in ELSP handler case which was to optimize scanning earlier instead of in gvt submission thread, so request alloc and add was splitting then which is against right process. This trys to do a partial revert of that commit which still has workload request alloc helper and make sure shadow state population is handled after request alloc for target state buffer. v3: Fix missed workload status setting in request alloc error path v2: Fix dispatch workload err path that should add request after alloc anyway.

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.
