NFSv4.1: Clean ups for the device id cache
The fact that the global device id cache holds a reference to the nfs4_deviceid_node until it is invisible to rcu lookups implies that we can always assume that the reference count is non-zero in _find_get_deviceid. Also clean up nfs4_put_deviceid_node and the removal of the device id from the cache. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
