scsi: sd_zbc: Fix sd_zbc_check_zone_size() error path
If a drive with variable zone sizes or an invalid last zone size is detected, the local variable this_zone_blocks is set to 0 and early return from the function triggered, but this does not result in an error return. The local variable zone_blocks must be set to 0 for an error to be returned.
