Coverity notes that the code at the end of the loop in
bmdma_prepare_buf() is unreachable. This is because in commit
9fbf0fa81fca8f527 ("ide: remove hardcoded 2GiB transactional limit")
we removed the only codepath in the loop which could "break" out of
it, but didn't notice that this meant we should also remove the code
at the end of the loop.
Remove the dead code.
