client: Handle parcel-not-checked-out in hoard()

- Move handling of the parcel-not-checked-out case from isr_hoard() to
hoard(), since it will never occur with "isr disconnect"

- Make "isr hoard" somewhat less verbose in the not-checked-out case

- Don't download parcel.cfg twice in the not-checked-out case
