[USETUP] Sprinkle some INF_FreeData() calls to balance the INF_GetData() /
INF_GetDataField() calls.
They currently do nothing, since the getter functions don't actually
capture (copy) the strings but merely return pointers to read-only strings.
But the calls are placed here for consistency, because if one day the
getters' implementation is changed so that strings are captured, it would
then be needed to free the allocated buffers.
In addition, fix a buggy call to INF_GetData() -- should be instead
INF_GetDataField() -- in AddSectionToCopyQueue().
