Move initialization of submission-related spinlock, lists and workers to init_early. This fixes an issue where if the GuC init fails we might still try to get the lock in the context cleanup code. Note that it is safe to call the GuC context cleanup code even if the init failed because all contexts are initialized with an invalid GuC ID, which will cause the GuC side of the cleanup to be skipped, so it is easier to just make sure the variables are initialized than to special case the cleanup to handle the case when they're not.

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.
