block: introduce bio_iov_iter_set()
In preparation to supporting dma-buf backed iterators and bios,
introduce bio_iov_iter_set() which attempts to set up the bio directly
from the given iterator. For now, it only supports bvec and expects
users to check the result and fall back to other means if fails, but
later we'll add more types.
