nfsd/blocklayout: pretend we can send deviceid notifications
Commit df52699e4fcef ("NFSv4.1: Don't cache deviceids that have no notifications") causes the Linux NFS client to stop caching deviceid's unless a server pretends to support deviceid notifications. While this behavior is stupid and the language around this area in rfc5661 is a mess carified by an errata that I submittted, Trond insists on this behavior. Not caching deviceids degrades block layout performance massively as a GETDEVICEINFO is fairly expensive. So add this hack to make the Linux client happy again.
