scsi: scsi_debug: Fix do_device_access() handling of unexpected SG copy length
If the sg_copy_buffer() call returns less than sdebug_sector_size, then
we drop out of the copy loop. However, we still report that we copied
the full expected amount, which is not proper.
Fix by keeping a running total and return that value.
