[SCSI] tmscsim: remove bogus endianness conversions

cpu_to_le32 endianness conversions in tmscsim.c, followed by
arithmetic operations don't look correct. Besides, {in,out}[wl]
already perform the necessary conversions. Further, bus addresses
of request buffers are guaranteed to be (mapped) under 4G by
current scsi- and block-layer defaults. This could be explicitly
enforced by using blk_queue_bounce_limit(), which, however,
doesn't seem to be the common practice among SCSI drivers.
