Several important steps during device scan depend on SCSI type of the device. For example, max_transfer property is only determined and assigned if the device has the type of TYPE_DISK. Host-managed ZBC disks retain most of the properties of regular SCSI drives, but they have their own SCSI device type, 0x14. This prevents the proper assignment of max_transfer property for HM-zoned devices in scsi-generic driver leading to I/O errors if the maximum i/o size calculated at the guest exceeds the host value. To fix this, define TYPE_ZBC to have the standard value from SCSI ZBC standard spec. Several scan steps that were previously done only for TYPE_DISK devices, are now performed for the SCSI devices having TYPE_ZBC too.
