xprtrdma: Enable swap-on-NFS/RDMA
After adding a swapfile on an NFS/RDMA mount and removing the normal swap partition, I was able to push the NFS client well into swap without any issue. I forgot to swapoff the NFS file before rebooting. This pinned the NFS mount and the IB core and provider, causing shutdown to hang. I think this is expected and safe behavior. Probably shutdown scripts should "swapoff -a" before unmounting any filesystems.
