[intel] Rename lost_hardware vtbl entry to new_batch.

Both drivers have ended up relying on lost_hardware being called after each
batch buffer, so update the name.  This removes one of the calls on 965 whic
h was outside of the batchbuffer handling code and just duplicating what had
already happened through batchbuffer handling.
