The previous code only support one queue, and we need
to support MQ in vhost user block device. This patch
can work with SPDK with MQ setting.

If we expect the vhost-user-blk device to be used for booting a VMM
along with the firmware, then need the device to support being reset.
In the vhost-user context, this means the backend needs to be informed
the vrings are disabled and stopped, and the owner needs to be reset
too.

vhost-user-blk has better performance than virtio-blk, so we need
add vhost-user-blk support with SPDK in Rust-based VMMs.

As mentioned in the vhost-user specification, each ring is initialized
in a stopped state. This means each ring should be enabled only after
it has been correctly initialized.

This patch factorizes the existing virtio-fs code by relying onto the
common code part of the vhost_user module in the vm-virtio crate.
In details, it factorizes the vhost-user setup, and reuses the error
types defined by the module instead of defining its own types.

vhost-user-net introduced a new module vhost_user inside the vm-virtio
crate. Because virtio-fs is actually vhost-user-fs, it belongs to this
new module and needs to be moved there.

vhost-user framwork could provide good performance in data intensive
scenario due to the memory sharing mechanism. Implement vhost-user-net
device to get the benefit for Rust-based VMMs network.
