Subject: [PATCH] ppc/vof: Fix missed fields in VOF cleanup
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

cheery-pick from 7b8589d7ce7e23f26ff53338d575a5cbd7818e28

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.
