block: move internal_tag to same cache line as tag
Since we removed cmd_type, we now have a hole in the struct. Move the internal_tag member to the same cacheline as tag, since we use them at the same time. This doesn't fix the hole, just moves it elsewhere. Signed-off-by: Jens Axboe <axboe@fb.com>
