Subject: [PATCH] dm: Remove redundant flush_workqueue() calls
Git-commit: ea3dba305252b4b3248836f2e1932d7a1aec647c
Patch-mainline: v5.16-rc1
References: jsc#PED-2765

destroy_workqueue() already drains the queue before destroying it, so
there is no need to flush it explicitly.

Remove the redundant flush_workqueue() calls.

This was generated with coccinelle:
