macio: fix overflow in lba to offset conversion for ATAPI devices
As the IDEState lba field is an int32_t, make sure we cast to int64_t before
shifting to calculate the offset. Otherwise we end up with an overflow when
trying to access sectors beyond 2GB as can occur when using DVD images.
[Maintainer edit: fixed extraneous parentheses. --js]
