Add a iomap_bio_submit_read_endio helper factored out of
iomap_bio_submit_read to that all ->submit_read implementations for
iomap_read_ops that use iomap_bio_read_folio_range can shared the
logic.
Right now that logic is mostly trivial, but already has a bug for XFS
because the XFS version is too trivial: file system integrity validation
needs a workqueue context and thus can't happen from the default iomap
bi_end_io I/O handler. Unfortunately the iomap refactoring just before
fs integrity landed moved code around here and the call go misplaced,
meaning it never got called. The PI information still is verified by
the block layer, but the offloading is less efficient (and the future
userspace interface can't get at it).
