Subject: ppc/vof: Fix missed fields in VOF cleanup

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.
