From: GuoHan Zhao <[email protected]>

vhost-user-base stores the VirtQueue pointers in a GPtrArray, but its
cleanup helper only deletes the VirtQueues and leaves the array itself
allocated.

Free the GPtrArray after deleting the queues and clear the pointer so
cleanup remains safe if the error path reaches it with no queues to
release.

Fixes: 6275989647ef (virtio: split into vhost-user-base and vhost-user-device)
