qapi: handle visitor->type_size() in QapiDeallocVisitor
visit_type_size() requires either visitor->type_size() or
visitor_uint64() to be implemented, otherwise a NULL function pointer is
invoked.
It is possible to trigger this crash as follows:
$ qemu-system-x86_64 -netdev tap,sndbuf=0,id=netdev0 \
-device virtio-blk-pci,netdev=netdev0
The 'sndbuf' option has type "size".
