fixup for "fix mscpool cleanup (fixes LCLS tests)"

For the VTY "Unknown Command" code path, we must actually call 'repeat', to
avoid racey VTY behavior from cruft stuck in the VTY pipe.

The missing 'repeat' caused massive random fallout in the 'latest' builds,
which often hits the 'Unknown Command' code path; fixed by this patch.
