related: fix inconsistencies in result type references
This patch is a response to errors found in those type
references now that our library allows for validation.
In two cases, former assignments to a result structure
could no longer employ that VAL macro if validation is
active. Thus, direct reference to some stack was used.
For the record, those instances were to be found here:
. ps - uses PIDS_extra to store the cooked pcpu values
. top - uses PIDS_extra to store the forest view level
