io_uring/rsrc: check for nonconsecutive pages
commit 776617db upstream. Pages that are from the same folio do not necessarily need to be consecutive. In that case, we cannot consolidate them into a single bvec entry. Before applying the huge page optimization from commit 57bebf80 ("io_uring/rsrc: optimise registered huge pages"), check that the memory is actually consecutive.
