block: Clean up the code used to generate and verify integrity metadata
Instead of the "operate" parameter we pass in a seed value and a pointer to a function that can be used to process the integrity metadata. The generation function is changed to have a return value to fit into this scheme. Signed-off-by: Martin K. Petersen <martin.petersen@oracle.com> Reviewed-by: Sagi Grimberg <sagig@mellanox.com> Signed-off-by: Jens Axboe <axboe@fb.com>
