scsi-generic: Fix HM-zoned device scan
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.
