hw/scsi/lsi53c895a: Use deposit32 rather than handcoded shift/mask
Use deposit32() rather than handcoded shifts/masks to update the
scratch registers. This is cleaner and incidentally avoids a clang
sanitizer complaint ("runtime error: left shift of 255 by 24 places
cannot be represented in type 'int'").
