Rob Bradford f09ab0898d vmm: config: Reject rate limiting with vhost_user
Rate limiting is implemented in the virtio device layer and does not
apply to vhost-user devices which delegate I/O handling to an external
process.

Add validation to reject configurations where vhost_user is enabled
along with rate limiting options (bw_size, ops_size, or
rate_limit_group) for both disk and network devices.

This prevents users from mistakenly configuring rate limiting that would
be silently ignored when using vhost-user backends.
