Thomas Haller 447dc874ce config: remove nm_config_data_get_value_cached() 
It has almost no callers, and it is a bit of a strange API. Let's
not cache the last accessed value inside NMConfigData. Instead, free
it right after use. It was not reused anyway, it only hangs around
as convenience for the caller.
