[Why] When 2 threads are doing commit_tail parallelly, one thread could commit new streams to dc state but another thread remove it from dc right away. [How] If we don't have new dm state change from commit_check, then we should not call dc_commit_streams() in commit_tail. A new function amdgpu_dm_commit_streams() is introduced to refator dc_commit_stream() adjacent code and fix this issue.

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.
