nvdimm: virtio_pmem: publish done with release/acquire
virtio_pmem_host_ack() publishes the device response by setting done and
waking the submitter. The submitter reads resp.ret after wait_event()
observes done.
Use smp_store_release() on done and smp_load_acquire() in the wait
condition so the response read is ordered after completion.
