The net_vhost PMD exposes queue state independently of port link state. Distribute workers only across active guest receive virtqueues and clear the state on disconnect so reconnects cannot retain stale queues. Signed-off-by: Harrison Caldicott <harrison@itsfubar.com.au>

Summary
Problem
A net_vhost device exposes its configured queue count before QEMU enables every guest virtqueue. Grout currently assigns workers across all configured TX queues, so a multiqueue guest can have packets sent to an inactive queue. A single queue hides the problem.
Validation
