From: Tom Yan <tom.ty89@xxxxxxxxx>
As of commit ca369d51b3e1649be4a72addd6d6a168cfb3f537, max_sectors
(rw_max) of a scsi disk can be as high as SD_DEF_XFER_BLOCKS.
Therefore, bump SCSI_DEFAULT_MAX_SECTORS to 65535 to make hosts
that do not have max_sectors set in their templates benefit
from the commit.
Hosts that are not capable of handling SCSI_DEFAULT_MAX_SECTORS
should have max_sectors set in their templates (like usb-storage
does in scsiglue.c).
