Remove the return value from vcore_request_more()

For a long time now the return value was of dubious value - you were never
really guaranteed that you were the one who executed the poke, so it was
possible for you to get a 0 back (success) but the call actually failed
under the hood.

Of course, none of the tests really had that issue.  vcore_request_* will
just panic internally on any error.
