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 3df49967f6 ("block: flush the
integrity workqueue in blk_integrity_unregister").
