[Why] By passing through the dm_determine_update_type_for_commit for atomic commits that can be done asynchronously we are incurring a performance penalty by locking access to the global private object and holding that access until the end of the programming sequence. This is also allocating a new large dc_state on every access in addition to retaining all the references on each stream and plane until the end of the programming sequence. [How] Shift the determination for async update before validation. Return early if it's going to be an async update.

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.
