Ming Lei 3c892a098b block: bounce: don't access bio->bi_io_vec in copy_to_high_bio_irq ...

Firstly this patch introduces BVEC_ITER_ALL_INIT for iterating one bio
from start to end.

As we need to support multipage bvecs, don't access bio->bi_io_vec
in copy_to_high_bio_irq(), and just use the standard iterator for that.
