vhost: Remove unused vhost_dev_{load|save}_inflight

Browse source 
vhost_dev_load_inflight and vhost_dev_save_inflight have been
unused since they were added in 2019 by:

5ad204bf2a ("vhost-user: Support transferring inflight buffer between qemu and backend")

Remove them, and their helper vhost_dev_resize_inflight.
