Change NotFound to InstanceNotFound in server_diagnostics.py

According to the get() method in nova/compute/api.py,
the index() method in nova/api/openstack/compute/
contrib/server_diagnostics.py should catch the
InstanceNotFound, rather than the NotFound.
This patch just applies to V2 API, V3 API is already
catching InstanceNotFound.
