This prevents integer overflow when converting the request queue's max_sectors from sectors to bytes. However, this is a preparation for extending the data type of max_sectors in struct Scsi_Host and scsi_host_template. So, it is impossible to happen this integer overflow for now, because SCSI low-level drivers can not specify max_sectors greater than 0xffff due to the data type limitation.
