[ Upstream commit e8bc14d116aeac8f0f133ec8d249acf4e0658da7 ]
Now that there are no indirect calls for PI processing there is no way to dereference a NULL pointer here. Additionally drivers now always freeze the queue (or in case of stacking drivers use their internal equivalent) around changing the integrity profile.
This is effectively a revert of commit 3df49967f6f1 ("block: flush the integrity workqueue in blk_integrity_unregister").
