[OPENPROMIO]: Handle current_node being NULL correctly.
If the user tries to traverse to the next node of the
last node, we get NULL in current_node and a zero phandle
returned. That's fine, but if the user tries to obtain
properties in that state, we try to dereference a NULL
pointer in the downcall to the of_*() routines.
So protect against that.
