io_uring/rsrc: check for nonconsecutive pages
commit 776617db78c6d208780e7c69d4d68d1fa82913de 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 57bebf807e2a
("io_uring/rsrc: optimise registered huge pages"), check that the memory
is actually consecutive.
