NFSv4.1: Use the correct hostname in the client identifier string
Trond Myklebust [Mon, 30 Apr 2012 16:04:58 +0000 (12:04 -0400)]
We need to use the hostname of the process that created the nfs_client.
That hostname is now stored in the rpc_client->cl_nodename.

Also remove the utsname()->domainname component. There is no reason
to include the NIS/YP domainname in a client identifier string.
