drivers: scsi: fix double decrement of block count in 64-bit LBA path
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.
