    ppc/vof: Fix missed fields in VOF cleanup
    
    Failing to reset the of_instance_last makes ihandle allocation continue
    to increase, which causes record-replay replay fail to match the
    recorded trace.
    
    Not resetting claimed_base makes VOF eventually run out of memory after
    some resets.
