block, bfq: Reorder struct bfq_iocq_bfqq_data
The size of struct bfq_iocq_bfqq_data can be reduced by moving a few
fields around.
On a x86_64, with allmodconfig, this shrinks the size from 144 to 128
bytes. The main benefit is to reduce the size of struct bfq_io_cq from
1360 to 1232.
This structure is stored in a dedicated slab cache. So reducing its size
improves cache usage.
