The block layer provides emulation of zone management operations targeting all zones of a zoned block device only for the zone reset operation (REQ_OP_ZONE_RESET). In order to correctly implement exporting of zoned block devices with NVMeOF, emulating zone management operations targeting all zones of a device is also necessary for the open, close and finish zone operations (REQ_OP_ZONE_OPEN, REQ_OP_ZONE_CLOSE and REQ_OP_ZONE_FINISH). Instead of duplicating the code, export the existing helper from block layer so we can use a bio chaining pattern that is present in the block layer for REQ_OP_ZONE RESET all emulation in the NVMeOF zoned block device backend.
