[GIT PULL] workqueue changes for v5.15-rc1

[Tejun Heo]

Hello, Linus.

There is a long-standing subtle destroy_workqueue() bug where a workqueue
can be destroyed while internal work items used for flushing are still in
flight. Lai fixed it by assigning a flush color to the internal work items
so that they are correctly waited for during destruction.

Other than that, all are minor cleanups.

Thanks.
