The scsi_read function incorrectly decrements the block count twice when handling large disks that trigger the CONFIG_SYS_64BIT_LBA code path (reads beyond block 268,435,455). The variable 'blks' was being decremented both inside the 64-bit LBA block and after the successful scsi_exec() call, causing incorrect block count tracking and data abort errors on large capacity disks.
