The req_iterator just happens to have a similar fields to what the dma
iterator needs, but we're not necessarily iterating a bio_vec here. Have
the dma iterator define its private fields directly. It also helps to
remove eyesores like "iter->iter.iter".

This will make it easier to add different bvec sources, like for
upcoming integrity support. It also makes iterating "special" payloads
more common with iterating normal data bi_io_vecs.

In preparing for integrity dma mappings, we can't rely on the request
flag because data and metadata may have different mapping types.

It's not serving any particular purpose anymore. pci_p2pdma_state()
already has all the appropriate checks, so the flag isn't guarding
anything.

In preparing for dma mapping integrity metadata, move the common dma
setup to a helper.

Provide integrity metadata helpers equivalent to the data payload
helpers for iterating a request for dma setup.

Signed-off-by: Keith Busch <[email protected]>

Aligns data and metadata to the similar dma mapping scheme and removes
one more user of the scatter-gather dma mapping.
