[dpdk-dev] [PATCH 3/3] vhost: Fix RESET_OWNER handling not to free virtqueue

[Tetsuya Mukawa]

When RESET_OWNER message is issued, vhost backend should not clear and
free virtqueue memories. This is because vhost backend should handle
GET_VRING_BASE message followed by the RESET_OWNER, so still vhost
backend need to access virtqueue memories.
These memories should be freed when SET_MEM_TABLE message is issued,
and vhost library has already had such a functionality.
