It is possible that we call pagefault_single_data_segment() with a MKey
that belongs to a memory region which is not on demand (i.e. pinned
pages). This can happen if, for instance, a WQE that points to multiple
MRs where some of them are ODP MRs and some are not. In this case we
don't need to handle this MR in the ODP context besides reporting success.
Otherwise the code will call pagefault_mr() which will do to_ib_umem_odp()
on a non-ODP MR and thus access out of bounds.
