block: remove the blk_flush_integrity call in blk_integrity_unregister

Browse source 
[ 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").
