vmm_vhost: vhost_user: Drop recv_data() from Endpoint trait

By modifying the interface of `Endpoint::recv_into_bufs()` slightly,
`Endpoint::recv_data()` can be moved to `EndpointExt` trait.
This means a new device struct will be required to implement less
methods.

BUG=none
TEST=run vhost-user block device

crosvm - The Chrome OS Virtual Machine Monitor

crosvm is a virtual machine monitor (VMM) based on Linux’s KVM hypervisor, with a focus on simplicity, security, and speed. crosvm is intended to run Linux guests, originally as a security boundary for running native applications on the Chrome OS platform. Compared to QEMU, crosvm doesn’t emulate architectures or real hardware, instead concentrating on paravirtualized devices, such as the virtio standard.

crosvm is currently used to run Linux/Android guests on Chrome OS devices.
