Since the subroutine is rather simple, and with only a single
reference in a single file, it would be best to just pull
the test inline and delete it. This would also remove some
inefficient code.

if (!iova_in_pmem(mr, iova, length) {
pr_err("Cannot set IB_ACCESS_FLUSH_PERSISTENT for non-pmem memory\n");
mr->umem = NULL;
err = -EINVAL;
goto err_release_umem;
mr-> ibmr.is_pmem = true;
