NFSv4.1: Fix uninitialised variable in devicenotify

Browse Source 
[ Upstream commit b05bf5c63b326ce1da84ef42498d8e0e292e694c ]

When decode_devicenotify_args() exits with no entries, we need to
ensure that the struct cb_devicenotifyargs is initialised to
{ 0, NULL } in order to avoid problems in
nfs4_callback_devicenotify().
